Description:
------------
gmmktime() without any parameters returns the wrong time. My time zone is GMT-8, so gmmktime() should be local time PLUS 8 hours.  Instead it returns local time minus 8 hours.  This is different from the DST/summer time problem previously reported.

My expected/actuals results are from a server on Pacific Time, but I also tried this on a web host in Hong Kong (ICDSoft), running PHP 4.4.2 and GMT is similarly offset in the wrong direction from Hong Kong local time.

Reproduce code:
---------------
   echo "<p> PHP version: " . phpversion() . "</p>";
   echo "<p>server time=" . date( "m/d/Y g:i A" )
      . " " . mktime() 
      . "   server GMT=" . date( "m/d/Y g:i A", gmmktime() )
      . " " . gmmktime()
      . "   time zone setting=GMT" . date("O"). "</p>";

Expected result:
----------------
PHP version: 4.4.2

server time=02/11/2006 7:58 AM 1139702295 server GMT=02/11/2006 03:58 PM 1139644695 time zone setting=GMT-0800


Actual result:
--------------
PHP version: 4.4.2

server time=02/11/2006 7:58 AM 1139673495 server GMT=02/10/2006 11:58 PM 1139644695 time zone setting=GMT-0800

I don't have my own web server. I'm using PHP at a web host. Can you try it on the latest build with the sample code I provided?
