From: vaughn at solarword dot net
Operating system: Windows NT XANADU 5.2 build 3790
PHP version: 5.2.1
PHP Bug Type: Date/time related
Bug description: putenv("TZ=xxxx") doesn't reset correctly

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"
