timespec_get(struct timespec *ts, int base);

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

The base TIME_UTC returns the time since the Epoch. This time is expressed in seconds and nanoseconds since midnight (0 hour), January 1, 1970. In OpenBSD, this corresponds to CLOCK_REALTIME.

The timespec_get function returns the passed value of base if successful, otherwise 0 on failure.

The timespec_get function with a base of TIME_UTC conforms to ISO/IEC 9899:2011 (“ISO C11”).
