Overview

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.

Return value

On success, zero is returned. On error, -1 is returned, and errno is set to indicate the error.

Errors

EFAULT

Error in getting information from user space.

EPERM

The calling process has insufficient privilege. Under Linux, the CAP_SYS_TIME privilege is required.
