NAME
|
|
time, stime - get/set date and time
|
|
|
|
SYNOPSIS
|
|
#include <sys/types.h>
|
|
#include <time.h>
|
|
|
|
time_t time(time_t *tp)
|
|
int stime(time_t *tp)
|
|
|
|
DESCRIPTION
|
|
The system's notion of the current Greenwich time is obtained with the
|
|
time call, and set with the stime call. The time is expressed in seconds
|
|
since midnight (0 hour), January 1, 1970. The time is both returned by
|
|
time and stored in the variable pointed to by tp unless tp is the null
|
|
pointer.
|
|
|
|
Stime obtains the time to set from the variable pointed to by tp.
|
|
|
|
Only the super-user may set the time of day.
|
|
|
|
RETURN
|
|
A 0 return value from stime indicates that the call succeeded. Time
|
|
returns the current time on success. A -1 return value indicates an
|
|
error occurred, and in this case an error code is stored into the global
|
|
variable errno.
|
|
|
|
ERRORS
|
|
The following error codes may be set in errno:
|
|
|
|
[EFAULT] The tp address referenced invalid memory.
|
|
|
|
[EPERM] A user other than the super-user attempted to set the
|
|
time.
