DESCRIPTION

The timespec_get() function shall set the interval pointed to by ts to hold the current calendar time based on the specified time base.

^[CX] If base is TIME_UTC, the members of ts shall be set to the same values as would be set by a call to clock_gettime(CLOCK_REALTIME, ts). If the number of seconds will not fit in an object of type time_t, the function shall return zero.
