I've copied the files as I always have, and when I run install/upgrade.php I get the following:

Fatal error: Call to undefined function: date_default_timezone_set() in C:\inetpub\vhosts\game-master.net\httpdocs\pit\libs\ubbthreads.inc.php on line 33

try it yourself: http://www.game-master.net/pit/install/upgrade.php

I'm upgrading Version: 7.5.7 to the latest version 7.5.9

please help.
I've never had a problem upgrading UBB in the many years I have been using it.
