STIME(2) Linux Programmer's Manual STIME(2)

stime - set time

#include <time.h>
int stime(const time_t *t);

Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
Since glibc 2.19:
Glibc 2.19 and earlier:

NOTE: This function is deprecated; use clock_settime(2) instead.
stime() sets the system's idea of the time and date. The time, pointed to by t, is measured in seconds since the Epoch, 1970-01-01 00:00:00 +0000 (UTC). stime() may be executed only by the superuser.

On success, zero is returned. On error, -1 is returned, and errno is set appropriately.

Error in getting information from user space.
The calling process has insufficient privilege. Under Linux, the CAP_SYS_TIME privilege is required.


Starting with glibc 2.31, this function is no longer available to newly linked applications and is no longer declared in <time.h>.
