arUtilTimeSinceEpoch()

void arUtilTimeSinceEpoch	(	uint64_t *	sec,
		uint32_t *	usec
	)

Get the time in seconds since midnight (00:00:00), January 1, 1970, coordinated universal time (UTC).

Parameters

sec	Pointer to an unsigned 64-bit interger which will be filled with the seconds portion of the time, or NULL if this value is not required.
sec	Pointer to an unsigned 32-bit interger which will be filled with the microseconds portion the time or NULL if this value is not required. N.B.: The resolution of the returned time is system-specific, and is not guaranteed to have microsecond-resolution.
