Contains time information, expressed in seconds and nanoseconds.
#include <time.h>
typedef struct timespec
{
time_t tv_sec;
long tv_nsec;
} timespec_t, timestrc_t;
Specifies the whole number of seconds since the epoch.
Specifies the fraction of a second in nanoseconds. On NetWare, this will never be less than one millisecond (one million nanoseconds).
The synch.h file also defines the timespec structure to be a timestruct_t structure.
