OffsetTime

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

A time with an offset from UTC/Greenwich in the ISO-8601 calendar system, such as 10:15:30+01:00.

OffsetTime is an immutable date-time object that represents a time, often viewed as hour-minute-second-offset. This class stores all time fields, to a precision of nanoseconds, as well as a zone offset. For example, the value "13:45.30.123456789+02:00" can be stored in an OffsetTime.

Fields

public static final OffsetTime MAX

The maximum supported OffsetTime, '23:59:59.999999999-18:00'. This is the time just before midnight at the end of the day in the minimum offset (larger negative offsets are later on the time-line). This combines LocalTime.MAX and ZoneOffset.MIN. This could be used by an application as a "far future" date.

public static final OffsetTime MIN

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

Public Methods

public Temporal adjustInto (Temporal temporal)

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

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

The adjustment is equivalent to using Temporal.with(TemporalField, long) twice, passing 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 = thisOffsetTime.adjustInto(temporal);
   temporal = temporal.with(thisOffsetTime);

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 OffsetDateTime atDate (LocalDate date)

Combines this time with a date to create an OffsetDateTime.

This returns an OffsetDateTime formed from this time and the specified date. All possible combinations of date and time are valid.

Parameters

date	the date to combine with, not null

Returns

the offset date-time formed from this time and the specified date, not null

public int compareTo (OffsetTime other)

Compares this OffsetTime to another time.

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

For example, the following is the comparator order:

10:30+01:00
11:00+01:00
12:00+02:00
11:30+01:00
12:00+01:00
12:30+01:00

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

To compare the underlying local time of two TemporalAccessor instances, use ChronoField.NANO_OF_DAY as a comparator.

Parameters

other	the other time to compare to, not null

Returns

the comparator value, negative if less, positive if greater

Throws

NullPointerException	if `other` is null

public boolean equals (Object obj)

Checks if this time is equal to another time.

The comparison is based on the local-time and the offset. To compare for the same instant on the time-line, use isEqual(OffsetTime).

Only objects of type OffsetTime are compared, other types return false. To compare the underlying local time of two TemporalAccessor instances, use ChronoField.NANO_OF_DAY as a comparator.

Parameters

obj	the object to check, null returns false

Returns

true if this is equal to the other time

public String format (DateTimeFormatter formatter)

Formats this time using the specified formatter.

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

Parameters

formatter	the formatter to use, not null

Returns

the formatted time string, not null

Throws

DateTimeException	if an error occurs during printing

public static OffsetTime from (TemporalAccessor temporal)

Obtains an instance of OffsetTime from a temporal object.

This obtains an offset 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 OffsetTime.

The conversion extracts and combines the ZoneOffset and the LocalTime from the temporal object. 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, OffsetTime::from.

Parameters

temporal	the temporal object to convert, not null

Returns

the offset time, not null

Throws

DateTimeException	if unable to convert to an `OffsetTime`

public int get (TemporalField field)

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

This queries this 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 time, except NANO_OF_DAY and MICRO_OF_DAY 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 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 time as a long.

This queries this 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 time. All other ChronoField instances will throw an UnsupportedTemporalTypeException.

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

Returns

a suitable hash code

public boolean isAfter (OffsetTime other)

Checks if the instant of this OffsetTime is after that of the specified time applying both times to a common date.

This method differs from the comparison in Comparable.compareTo(T) in that it only compares the instant of the time. This is equivalent to converting both times to an instant using the same date and comparing the instants.

Parameters

other	the other time to compare to, not null

Returns

true if this is after the instant of the specified time

public boolean isBefore (OffsetTime other)

Checks if the instant of this OffsetTime is before that of the specified time applying both times to a common date.

Returns

true if this is before the instant of the specified time

public boolean isEqual (OffsetTime other)

Checks if the instant of this OffsetTime is equal to that of the specified time applying both times to a common date.

This method differs from the comparison in Comparable.compareTo(T) and equals(Object) in that it only compares the instant of the time. This is equivalent to converting both times to an instant using the same date and comparing the instants.

Parameters

other	the other time to compare to, not null

Returns

true if this is equal to the instant of the specified 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 offset-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

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

If the field is a ChronoField then the query is implemented here. The supported fields are:

NANO_OF_SECOND
NANO_OF_DAY
MICRO_OF_SECOND
MICRO_OF_DAY
MILLI_OF_SECOND
MILLI_OF_DAY
SECOND_OF_MINUTE
SECOND_OF_DAY
MINUTE_OF_HOUR
MINUTE_OF_DAY
HOUR_OF_AMPM
CLOCK_HOUR_OF_AMPM
HOUR_OF_DAY
CLOCK_HOUR_OF_DAY
AMPM_OF_DAY
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 time, false if not

public OffsetTime minus (TemporalAmount amountToSubtract)

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

This returns an OffsetTime, based on this one, with the specified amount subtracted. The amount is typically 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 OffsetTime based on this time with the subtraction made, not null

Throws

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

public OffsetTime minus (long amountToSubtract, TemporalUnit unit)

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

This returns an OffsetTime, 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

public static OffsetTime now (ZoneId zone)

Obtains the current time from the system clock in the specified time-zone.

This will query the system clock to obtain the current time. Specifying the time-zone avoids dependence on the default time-zone. The offset will be calculated from the specified time-zone.

Using this method will prevent the ability to use an alternate clock for testing because the clock is hard-coded.

Parameters

zone	the zone ID to use, not null

Returns

the current time using the system clock, not null

public static OffsetTime now ()

Obtains the current time from the system clock in the default time-zone.

This will query the system clock in the default time-zone to obtain the current time. The offset will be calculated from the time-zone in the clock.

Using this method will prevent the ability to use an alternate clock for testing because the clock is hard-coded.

Returns

the current time using the system clock and default time-zone, not null

public static OffsetTime now (Clock clock)

Obtains the current time from the specified clock.

This will query the specified clock to obtain the current time. The offset will be calculated from the time-zone in the clock.

Using this method allows the use of an alternate clock for testing. The alternate clock may be introduced using dependency injection.

Parameters

clock	the clock to use, not null

Returns

the current time, not null

public static OffsetTime of (int hour, int minute, int second, int nanoOfSecond, ZoneOffset offset)

Obtains an instance of OffsetTime from an hour, minute, second and nanosecond.

This creates an offset time with the four specified fields.

This method exists primarily for writing test cases. Non test-code will typically use other methods to create an offset time. LocalTime has two additional convenience variants of the equivalent factory method taking fewer arguments. They are not provided here to reduce the footprint of the API.

Parameters

hour	the hour-of-day to represent, from 0 to 23
minute	the minute-of-hour to represent, from 0 to 59
second	the second-of-minute to represent, from 0 to 59

time	the local time, not null
offset	the zone offset, not null

Returns

the offset time, not null

public static OffsetTime ofInstant (Instant instant, ZoneId zone)

Obtains an instance of OffsetTime from an Instant and zone ID.

This creates an offset time with the same instant as that specified. Finding the offset from UTC/Greenwich is simple as there is only one valid offset for each instant.

The date component of the instant is dropped during the conversion. This means that the conversion can never fail due to the instant being out of the valid range of dates.

Parameters

instant	the instant to create the time from, not null
zone	the time-zone, which may be an offset, not null

Returns

the offset time, not null

public static OffsetTime parse (CharSequence text, DateTimeFormatter formatter)

Obtains an instance of OffsetTime from a text string using a specific formatter.

The text is parsed using the formatter, returning a time.

Parameters

formatter	the formatter to use, not null

Returns

the parsed offset time, not null

Throws

DateTimeParseException	if the text cannot be parsed

public static OffsetTime parse (CharSequence text)

Obtains an instance of OffsetTime from a text string such as 10:15:30+01:00.

The string must represent a valid time and is parsed using DateTimeFormatter.ISO_OFFSET_TIME.

Parameters

text	the text to parse such as "10:15:30+01:00", not null

Returns

the parsed local time, not null

Throws

DateTimeParseException	if the text cannot be parsed

public OffsetTime plus (TemporalAmount amountToAdd)

Returns a copy of this time with the specified amount added.

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

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

This instance is immutable and unaffected by this method call.

Parameters

amountToAdd	the amount to add, not null

Returns

an OffsetTime based on this time with the addition made, not null

Throws

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

public OffsetTime plus (long amountToAdd, TemporalUnit unit)

Returns a copy of this time with the specified amount added.

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

If the field is a ChronoUnit then the addition is implemented by LocalTime.plus(long, TemporalUnit). The offset is not part of the calculation and will be unchanged in the result.

If the field is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.addTo(Temporal, long) passing this as the argument. In this case, the unit determines whether and how to perform the addition.

This instance is immutable and unaffected by this method call.

Parameters

amountToAdd	the amount of the unit to add to the result, may be negative
unit	the unit of the amount to add, not null

Returns

an OffsetTime based on this time with the specified amount added, not null
