Identical to the <function>date</function> function except that
|
|
the time returned is Greenwich Mean Time (GMT). For example, when
|
|
run in Finland (GMT +0200), the first line below prints "Jan 01
|
|
1998 00:00:00", while the second prints "Dec 31 1997 22:00:00".

In the Microsoft Windows series of Operating Systems the system
|
|
libraries implementing this function are broken, so
|
|
<function>gmdate</function> does not support negative values
|
|
for the <parameter>timestamp</parameter>.
|
|

<para>

This problem does not occur in Unix/Linux Operating Systems, as the
|
|
system libraries behave as expected.

PHP cannot fix broken system libraries. Contact
|
|
your OS vendor for a fix to this and similar problems.
