NAME
     timespec_get - get current calendar time

LIBRARY

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
     expressed in seconds and nanoseconds since midnight (0 hour), January 1,
     1970.  In NetBSD, this corresponds to CLOCK_REALTIME.

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

SEE ALSO
     clock_gettime(2), gettimeofday(2), time(3)

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