Synopsis
#define _SVID_SOURCE /* glibc2 needs this */
#include <time.h>
int stime(time_t *t); |
Description
stime sets the system's idea of the time and date. Time, pointed to by t, is measured in seconds from 00:00:00 GMT January 1, 1970. stime() may only be executed by the super user.
Return Value
On success, zero is returned. On error, -1 is returned, and errno is set appropriately.
Errors
- EPERM
The caller is not the super-user.
Notes
Under glibc2, <time.h> only provides a prototype when _SVID_SOURCE is defined.
