Time-specification structure
Synopsis:
#include <time.h>
struct timespec {
time_t tv_sec;
long tv_nsec;
}
Description:
The timespec structure specifies a time in seconds and nanoseconds.
The members include:
- tv_sec
- The number of seconds.
If specifying an absolute time, this member is the number of seconds since 1970.
- tv_nsec
- Denotes the partial second beyond tv_sectv_sec, expressed as nanoseconds.
- For most uses, only values between 0 - 1e9 are valid.
