Description:
------------
Using Stock PHP5.2.1 msi package downloaded from php.net (Same bug appeared in php-4.3.11)  Apache version=2.0.53

Problem: The first time that TZ is set, that value becomes the new default for future php runs.

This doesn't appear to be like bug #37908 as the apache logs timestamps are not changed.

PHP Configure line:
cscript /nologo configure.js "--enable-snapshot-build" "--with-gd=shared" 

Apache config:
PHPIniDir "D:/PHP5/"
LoadModule php5_module "D:\\PHP5\\php5apache2.dll"
