struct timespec; | (since C11) |
Structure holding an interval broken down into seconds and nanoseconds.
time_t tv_sec | whole seconds (valid values are >= 0) |
long tv_nsec | nanoseconds (valid values are [0, 999999999]) |
#include <stdio.h>
#include <time.h>
#include <stdint.h>
int main(void)
{
struct timespec ts;
timespec_get(&ts, TIME_UTC);
char buff[100];
strftime(buff, sizeof buff, "%D %T", gmtime(&ts.tv_sec));
printf("Current time: %s.%09ld UTC\n", buff, ts.tv_nsec);
printf("Raw timespec.time_t: %jd\n", (intmax_t)ts.tv_sec);
printf("Raw timespec.tv_nsec: %09ld\n", ts.tv_nsec);
}Possible output:
Current time: 11/24/21 03:10:50.408191283 UTC Raw timespec.time_t: 1637723450 Raw timespec.tv_nsec: 408191283
