TIMESPEC_GET(3) Library Functions Manual TIMESPEC_GET(3) NAME timespec_get -- get current calendar time LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <time.h> int timespec_get(struct timespec *ts, int base); DESCRIPTION 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 ex- pressed in seconds and nanoseconds since midnight (0 hour), January 1, 1970. In FreeBSD, this corresponds to CLOCK_REALTIME. The base TIME_MONOTONIC returns a monotonically-increasing time since an unspecified point in the past. In FreeBSD, this corresponds to CLOCK_MONOTONIC. RETURN VALUES The timespec_get function returns the passed value of base if success- ful, otherwise 0 on failure. SEE ALSO clock_gettime(2), gettimeofday(2), time(3), timespec_getres(3) STANDARDS The timespec_get function with a base of TIME_UTC conforms to ISO/IEC 9899:2011 ("ISO C11").
