Provides access to system time and timers.
Macros
kSbTimeDay
One day in SbTime units (microseconds).
kSbTimeHour
One hour in SbTime units (microseconds).
kSbTimeMax
The maximum value of an SbTime.
kSbTimeMillisecond
One millisecond in SbTime units (microseconds).
kSbTimeMinute
One minute in SbTime units (microseconds).
kSbTimeNanosecondsPerMicrosecond
How many nanoseconds in one SbTime unit (microseconds).
kSbTimeSecond
One second in SbTime units (microseconds).
kSbTimeToPosixDelta
A term that can be added to an SbTime to convert it into the number of microseconds since the POSIX epoch.
Typedefs
SbTime
The number of microseconds since the epoch of January 1, 1601 UTC, or the number of microseconds between two times. Always microseconds, ALWAYS UTC.
Definition
typedef int64_t SbTime
SbTimeMonotonic
A number of microseconds from some point. The main property of this time is that it increases monotonically. It should also be as high-resolution a timer as we can get on a platform. So, it is good for measuring the time between two calls without worrying about a system clock adjustment. It's not good for getting the wall clock time.
Definition
typedef int64_t SbTimeMonotonic
Functions
SbTimeFromPosix
Converts microseconds from the POSIX epoch into an SbTime.
time: A time that measures the number of microseconds since January 1, 1970,
00:00:00, UTC.
Declaration
static SbTime SbTimeFromPosix(int64_t time)
SbTimeGetMonotonicNow
Gets a monotonically increasing time representing right now.
Declaration
SbTimeMonotonic SbTimeGetMonotonicNow()
SbTimeGetMonotonicThreadNow
Gets a monotonically increasing time representing how long the current thread has been in the executing state (i.e. not pre-empted nor waiting on an event). This is not necessarily total time and is intended to allow measuring thread execution time between two timestamps. If this is not available then SbTimeGetMonotonicNow() should be used.
Declaration
SbTimeMonotonic SbTimeGetMonotonicThreadNow()
SbTimeGetNow
Gets the current system time as an SbTime.
Declaration
SbTime SbTimeGetNow()
SbTimeIsTimeThreadNowSupported
Returns whether the current platform supports time thread now
Declaration
bool SbTimeIsTimeThreadNowSupported()
SbTimeNarrow
Safely narrows a number from a more precise unit to a less precise one. This function rounds negative values toward negative infinity.
Declaration
static int64_t SbTimeNarrow(int64_t time, int64_t divisor)
SbTimeToPosix
Converts SbTime into microseconds from the POSIX epoch.
time: A time that is either measured in microseconds since the epoch of
January 1, 1601, UTC, or that measures the number of microseconds between two
times.
Declaration
static int64_t SbTimeToPosix(SbTime time)
