<H2>DESCRIPTION</H2><PRE>
|
||||
The system's notion of the current Greenwich time is obtained with the
|
||||
<STRONG>time</STRONG> call, and set with the <STRONG>stime</STRONG> call. The time is expressed in seconds
|
||||
since midnight (0 hour), January 1, 1970. The time is both returned by
|
||||
<STRONG>time</STRONG> and stored in the variable pointed to by <EM>tp</EM> unless <EM>tp</EM> is the null
|
||||
pointer.
|
||||
|
||||
<STRONG>Stime</STRONG> obtains the time to set from the variable pointed to by <EM>tp</EM>.
|
||||
|
||||
Only the super-user may set the time of day.
|
||||
|
||||
|
||||
</PRE>
|
||||
<H2>RETURN</H2><PRE>
|
||||
A 0 return value from <STRONG>stime</STRONG> indicates that the call succeeded. <STRONG>Time</STRONG>
|
||||
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 <STRONG>errno</STRONG>.
|
||||
|
||||
|
||||
</PRE>
|
||||
<H2>ERRORS</H2><PRE>
|
||||
The following error codes may be set in <STRONG>errno</STRONG>:
|
||||
|
||||
[EFAULT] The <EM>tp</EM> address referenced invalid memory.
|
||||
|
||||
[EPERM] A user other than the super-user attempted to set the
|
||||
time.
