The time, pointed to by \fIt\fP, is measured in seconds since the Epoch, 1970-01-01 00:00:00 +0000 (UTC). .BR stime () may be executed only by the superuser. .SH RETURN VALUE On success, zero is returned. On error, \-1 is returned, and .I errno is set appropriately. .SH ERRORS .TP .B EFAULT Error in getting information from user space. .TP .B EPERM The calling process has insufficient privilege. Under Linux, the .B CAP_SYS_TIME privilege is required. .SH CONFORMING TO SVr4. .SH NOTES Starting with glibc 2.31, this function is no longer available to newly linked applications and is no longer declared in .IR . .SH SEE ALSO .BR date (1), .BR settimeofday (2), .BR capabilities (7) .SH COLOPHON This page is part of release 5.10 of the Linux .I man-pages project.
