Description:
------------
date_default_timezone_set('UTC') is not working as expected, date function returns 
time with -14400 seconds (-4 hours) from UTC.

I've run into this problem after moving into new server, had to set default 
timezone to GMT instead of UTC for the code to work correctly.

Test script:
---------------
$time = time();

date_default_timezone_set('UTC');
echo (date('h', $time) - gmdate('h', $time));

date_default_timezone_set('GMT');
echo "\n".(date('h', $time) - gmdate('h', $time));

Expected result:
----------------
0
0

Actual result:
--------------
-4
0

phpinfo() showed "Olson" Timezone Database Version as 0.system, so I used the 
command

$ pecl upgrade timezonedb

and added

extension=timezonedb.so
to php.ini

After restarting the server, the problem has been resolved with the new timezone 
DB version 2013.3
