Method gethrtime()
- Method
gethrtime
int gethrtime(void|int nsec) - Description
Return the high resolution real time since some arbitrary event in
the past. The time is normally returned in microseconds, but if
the optional argument nsec is nonzero it's returned in
nanoseconds.
It's system dependent whether or not this time is monotonic, i.e.
if it's unaffected by adjustments of the calendaric clock in the
system. System.REAL_TIME_IS_MONOTONIC tells what it is. Pike
tries to use monotonic time for this function if it's available.
- Note
The actual accuracy on many systems is significantly less than
microseconds or nanoseconds. See System.REAL_TIME_RESOLUTION .
