OffsetDateTime

public final class OffsetDateTime extends Object
implements Temporal TemporalAdjuster Comparable<OffsetDateTime> Serializable

A date-time with an offset from UTC/Greenwich in the ISO-8601 calendar system, such as 2007-12-03T10:15:30+01:00.

OffsetDateTime is an immutable representation of a date-time with an offset. This class stores all date and time fields, to a precision of nanoseconds, as well as the offset from UTC/Greenwich. For example, the value "2nd October 2007 at 13:45.30.123456789 +02:00" can be stored in an OffsetDateTime.

OffsetDateTime, ZonedDateTime and Instant all store an instant on the time-line to nanosecond precision. Instant is the simplest, simply representing the instant. OffsetDateTime adds to the instant the offset from UTC/Greenwich, which allows the local date-time to be obtained. ZonedDateTime adds full time-zone rules.

It is intended that ZonedDateTime or Instant is used to model data in simpler applications. This class may be used when modeling date-time concepts in more detail, or when communicating to a database or in a network protocol.

Fields

public static final OffsetDateTime MAX

The maximum supported OffsetDateTime, '[phone]T23:59:59.999999999-18:00'. This is the local date-time just before midnight at the end of the maximum date in the minimum offset (larger negative offsets are later on the time-line). This combines LocalDateTime.MAX and ZoneOffset.MIN. This could be used by an application as a "far future" date-time.

public static final OffsetDateTime MIN

The minimum supported OffsetDateTime, '-999999999-01-01T00:00:00+18:00'. This is the local date-time of midnight at the start of the minimum date in the maximum offset (larger offsets are earlier on the time-line). This combines LocalDateTime.MIN and ZoneOffset.MAX. This could be used by an application as a "far past" date-time.

Public Methods

public Temporal adjustInto (Temporal temporal)

Adjusts the specified temporal object to have the same offset, date and time as this object.

This returns a temporal object of the same observable type as the input with the offset, date and time changed to be the same as this.

The adjustment is equivalent to using Temporal.with(TemporalField, long) three times, passing ChronoField.EPOCH_DAY, ChronoField.NANO_OF_DAY and ChronoField.OFFSET_SECONDS as the fields.

In most cases, it is clearer to reverse the calling pattern by using Temporal.with(TemporalAdjuster):

   // these two lines are equivalent, but the second approach is recommended
   temporal = thisOffsetDateTime.adjustInto(temporal);
   temporal = temporal.with(thisOffsetDateTime);
 

This instance is immutable and unaffected by this method call.

Parameters

temporal	the target object to be adjusted, not null

Returns

• the adjusted object, not null

Throws

DateTimeException	if unable to make the adjustment
ArithmeticException	if numeric overflow occurs

public ZonedDateTime atZoneSameInstant (ZoneId zone)

Combines this date-time with a time-zone to create a ZonedDateTime ensuring that the result has the same instant.

This returns a ZonedDateTime formed from this date-time and the specified time-zone. This conversion will ignore the visible local date-time and use the underlying instant instead. This avoids any problems with local time-line gaps or overlaps. The result might have different values for fields such as hour, minute an even day.

To attempt to retain the values of the fields, use atZoneSimilarLocal(ZoneId). To use the offset as the zone ID, use toZonedDateTime().

Parameters

zone	the time-zone to use, not null

Returns

• the zoned date-time formed from this date-time, not null

public ZonedDateTime atZoneSimilarLocal (ZoneId zone)

Combines this date-time with a time-zone to create a ZonedDateTime trying to keep the same local date and time.

This returns a ZonedDateTime formed from this date-time and the specified time-zone. Where possible, the result will have the same local date-time as this object.

Time-zone rules, such as daylight savings, mean that not every time on the local time-line exists. If the local date-time is in a gap or overlap according to the rules then a resolver is used to determine the resultant local time and offset. This method uses ZonedDateTime.ofLocal(LocalDateTime, ZoneId, ZoneOffset) to retain the offset from this instance if possible.

Finer control over gaps and overlaps is available in two ways. If you simply want to use the later offset at overlaps then call ZonedDateTime.withLaterOffsetAtOverlap() immediately after this method.

To create a zoned date-time at the same instant irrespective of the local time-line, use atZoneSameInstant(ZoneId). To use the offset as the zone ID, use toZonedDateTime().

Parameters

zone	the time-zone to use, not null

Returns

• the zoned date-time formed from this date and the earliest valid time for the zone, not null

public int compareTo (OffsetDateTime other)

Compares this date-time to another date-time.

The comparison is based on the instant then on the local date-time. It is "consistent with equals", as defined by Comparable.

For example, the following is the comparator order:

1. 2008-12-03T10:30+01:00
2. 2008-12-03T11:00+01:00
3. 2008-12-03T12:00+02:00
4. 2008-12-03T11:30+01:00
5. 2008-12-03T12:00+01:00
6. 2008-12-03T12:30+01:00

Values #2 and #3 represent the same instant on the time-line. When two values represent the same instant, the local date-time is compared to distinguish them. This step is needed to make the ordering consistent with equals().

Parameters

other	the other date-time to compare to, not null

Returns

• the comparator value, negative if less, positive if greater

public boolean equals (Object obj)

Checks if this date-time is equal to another date-time.

The comparison is based on the local date-time and the offset. To compare for the same instant on the time-line, use isEqual(OffsetDateTime). Only objects of type OffsetDateTime are compared, other types return false.

Parameters

obj	the object to check, null returns false

Returns

• true if this is equal to the other date-time

public String format (DateTimeFormatter formatter)

Formats this date-time using the specified formatter.

This date-time will be passed to the formatter to produce a string.

Parameters

formatter	the formatter to use, not null

Returns

• the formatted date-time string, not null

Throws

DateTimeException	if an error occurs during printing

public static OffsetDateTime from (TemporalAccessor temporal)

Obtains an instance of OffsetDateTime from a temporal object.

This obtains an offset date-time based on the specified temporal. A TemporalAccessor represents an arbitrary set of date and time information, which this factory converts to an instance of OffsetDateTime.

The conversion will first obtain a ZoneOffset from the temporal object. It will then try to obtain a LocalDateTime, falling back to an Instant if necessary. The result will be the combination of ZoneOffset with either with LocalDateTime or Instant. Implementations are permitted to perform optimizations such as accessing those fields that are equivalent to the relevant objects.

This method matches the signature of the functional interface TemporalQuery allowing it to be used as a query via method reference, OffsetDateTime::from.

Parameters

temporal	the temporal object to convert, not null

Returns

• the offset date-time, not null

Throws

DateTimeException	if unable to convert to an OffsetDateTime

public int get (TemporalField field)

Gets the value of the specified field from this date-time as an int.

This queries this date-time for the value of the specified field. The returned value will always be within the valid range of values for the field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the query is implemented here. The supported fields will return valid values based on this date-time, except NANO_OF_DAY, MICRO_OF_DAY, EPOCH_DAY, PROLEPTIC_MONTH and INSTANT_SECONDS which are too large to fit in an int and throw a DateTimeException. All other ChronoField instances will throw an UnsupportedTemporalTypeException.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.getFrom(TemporalAccessor) passing this as the argument. Whether the value can be obtained, and what the value represents, is determined by the field.

Parameters

field	the field to get, not null

Returns

• the value for the field

Throws

DateTimeException	if a value for the field cannot be obtained or the value is outside the range of valid values for the field
UnsupportedTemporalTypeException	if the field is not supported or the range of values exceeds an int
ArithmeticException	if numeric overflow occurs

public int getDayOfMonth ()

Gets the day-of-month field.

This method returns the primitive int value for the day-of-month.

Returns

• the day-of-month, from 1 to 31

public DayOfWeek getDayOfWeek ()

Gets the day-of-week field, which is an enum DayOfWeek.

This method returns the enum DayOfWeek for the day-of-week. This avoids confusion as to what int values mean. If you need access to the primitive int value then the enum provides the int value.

Additional information can be obtained from the DayOfWeek. This includes textual names of the values.

Returns

• the day-of-week, not null

public int getDayOfYear ()

Gets the day-of-year field.

This method returns the primitive int value for the day-of-year.

Returns

• the day-of-year, from 1 to 365, or 366 in a leap year

public int getHour ()

Gets the hour-of-day field.

Returns

• the hour-of-day, from 0 to 23

public long getLong (TemporalField field)

Gets the value of the specified field from this date-time as a long.

This queries this date-time for the value of the specified field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the query is implemented here. The supported fields will return valid values based on this date-time. All other ChronoField instances will throw an UnsupportedTemporalTypeException.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.getFrom(TemporalAccessor) passing this as the argument. Whether the value can be obtained, and what the value represents, is determined by the field.

Parameters

field	the field to get, not null

Returns

• the value for the field

Throws

DateTimeException	if a value for the field cannot be obtained
UnsupportedTemporalTypeException	if the field is not supported
ArithmeticException	if numeric overflow occurs

public int getMinute ()

Gets the minute-of-hour field.

Returns

• the minute-of-hour, from 0 to 59

public Month getMonth ()

Gets the month-of-year field using the Month enum.

This method returns the enum Month for the month. This avoids confusion as to what int values mean. If you need access to the primitive int value then the enum provides the int value.

Returns

• the month-of-year, not null

See Also

• getMonthValue()

public int getMonthValue ()

Gets the month-of-year field from 1 to 12.

This method returns the month as an int from 1 to 12. Application code is frequently clearer if the enum Month is used by calling getMonth().

Returns

• the month-of-year, from 1 to 12

See Also

• getMonth()

public int getNano ()

Gets the nano-of-second field.

Returns

• the nano-of-second, from 0 to 999,999,999

Returns

• a suitable hash code

public boolean isAfter (OffsetDateTime other)

Checks if the instant of this date-time is after that of the specified date-time.

This method differs from the comparison in Comparable.compareTo(T) and equals(Object) in that it only compares the instant of the date-time. This is equivalent to using dateTime1.toInstant().isAfter(dateTime2.toInstant());.

Parameters

other	the other date-time to compare to, not null

Returns

• true if this is after the instant of the specified date-time

public boolean isBefore (OffsetDateTime other)

Parameters

other	the other date-time to compare to, not null

Returns

• true if this is before the instant of the specified date-time

public boolean isEqual (OffsetDateTime other)

Checks if the instant of this date-time is equal to that of the specified date-time.

This method differs from the comparison in Comparable.compareTo(T) and equals(Object) in that it only compares the instant of the date-time. This is equivalent to using dateTime1.toInstant().equals(dateTime2.toInstant());.

Parameters

other	the other date-time to compare to, not null

Returns

• true if the instant equals the instant of the specified date-time

public boolean isSupported (TemporalUnit unit)

Checks if the specified unit is supported.

This checks if the specified unit can be added to, or subtracted from, this date-time. If false, then calling the plus(long, TemporalUnit) and minus methods will throw an exception.

If the unit is a ChronoUnit then the query is implemented here. The supported units are:

• NANOS
• MICROS
• MILLIS
• SECONDS
• MINUTES
• HOURS
• HALF_DAYS
• DAYS
• WEEKS
• MONTHS
• YEARS
• DECADES
• CENTURIES
• MILLENNIA
• ERAS

All other ChronoUnit instances will return false.

If the unit is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.isSupportedBy(Temporal) passing this as the argument. Whether the unit is supported is determined by the unit.

Parameters

unit	the unit to check, null returns false

Returns

• true if the unit can be added/subtracted, false if not

public boolean isSupported (TemporalField field)

Checks if the specified field is supported.

This checks if this date-time can be queried for the specified field. If false, then calling the range, get and with(TemporalField, long) methods will throw an exception.

• PROLEPTIC_MONTH
• YEAR_OF_ERA
• YEAR
• ERA
• INSTANT_SECONDS
• OFFSET_SECONDS

All other ChronoField instances will return false.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.isSupportedBy(TemporalAccessor) passing this as the argument. Whether the field is supported is determined by the field.

Parameters

field	the field to check, null returns false

Returns

• true if the field is supported on this date-time, false if not

public OffsetDateTime minus (TemporalAmount amountToSubtract)

Returns a copy of this date-time with the specified amount subtracted.

This returns an OffsetDateTime, based on this one, with the specified amount subtracted. The amount is typically Period or Duration but may be any other type implementing the TemporalAmount interface.

The calculation is delegated to the amount object by calling TemporalAmount.subtractFrom(Temporal). The amount implementation is free to implement the subtraction in any way it wishes, however it typically calls back to minus(long, TemporalUnit). Consult the documentation of the amount implementation to determine if it can be successfully subtracted.

This instance is immutable and unaffected by this method call.

Parameters

amountToSubtract	the amount to subtract, not null

Returns

• an OffsetDateTime based on this date-time with the subtraction made, not null

Throws

DateTimeException	if the subtraction cannot be made
ArithmeticException	if numeric overflow occurs

public OffsetDateTime minus (long amountToSubtract, TemporalUnit unit)

Returns a copy of this date-time with the specified amount subtracted.

This returns an OffsetDateTime, based on this one, with the amount in terms of the unit subtracted. If it is not possible to subtract the amount, because the unit is not supported or for some other reason, an exception is thrown.

This method is equivalent to plus(long, TemporalUnit) with the amount negated. See that method for a full description of how addition, and thus subtraction, works.

This instance is immutable and unaffected by this method call.

Parameters

amountToSubtract	the amount of the unit to subtract from the result, may be negative
unit	the unit of the amount to subtract, not null

Returns

• an OffsetDateTime based on this date-time with the specified amount subtracted, not null

Throws

DateTimeException	if the subtraction cannot be made
UnsupportedTemporalTypeException	if the unit is not supported
ArithmeticException	if numeric overflow occurs

public OffsetDateTime minusDays (long days)

Returns a copy of this OffsetDateTime with the specified number of days subtracted.

This method subtracts the specified amount from the days field decrementing the month and year fields as necessary to ensure the result remains valid. The result is only invalid if the maximum/minimum year is exceeded.

For example, 2008-12-31 minus one day would result in 2009-01-01.

This instance is immutable and unaffected by this method call.

Parameters

days	the days to subtract, may be negative

Returns

• an OffsetDateTime based on this date-time with the days subtracted, not null

Throws

DateTimeException	if the result exceeds the supported date range

public OffsetDateTime minusHours (long hours)

Returns a copy of this OffsetDateTime with the specified number of hours subtracted.

This instance is immutable and unaffected by this method call.

Parameters

hours	the hours to subtract, may be negative

Returns

• an OffsetDateTime based on this date-time with the hours subtracted, not null

public OffsetDateTime minusMinutes (long minutes)

Returns a copy of this OffsetDateTime with the specified number of minutes subtracted.

This instance is immutable and unaffected by this method call.

Parameters

minutes	the minutes to subtract, may be negative

Returns

• an OffsetDateTime based on this date-time with the minutes subtracted, not null

Throws

DateTimeException	if the result exceeds the supported date range

public OffsetDateTime minusMonths (long months)

Returns a copy of this OffsetDateTime with the specified number of months subtracted.

This method subtracts the specified amount from the months field in three steps:

1. Subtract the input months from the month-of-year field
2. Check if the resulting date would be invalid
3. Adjust the day-of-month to the last valid day if necessary

For example, 2007-03-31 minus one month would result in the invalid date 2007-04-31. Instead of returning an invalid result, the last valid day of the month, 2007-04-30, is selected instead.
