install the newest XAMPP on my local Windows box. If it checks out ok, the upgrade goes to my NAS.
Interesting, so on your windows box running XAMPP w/PHP5.3.5 you've never seen this error in the Admin backend of Template Manager ->Warning: Invalid CRT parameters detected in J:\wampserver64\www\panacea\libraries\joomla\utilities\date.php on line 250
Apparently pre 5.3.0 versions accepted Windows backward method of dates better.
Thanks
