Time Zone Offset
for osCommerce Online Merchant v2.3
If your server is in a different time zone or country than you are selling in to and you would like to set the correct time zone on your server (requires PHP version 5.2+), edit the following two files:
Add in to them the following line:
This is to set the time zone for New Zealand, just find your own time zone from this web site http://php.net/manual/en/timezones.php and apply the correct one for your location.
Once you have uploaded those two files after editing and you're done!
The attached file only has these instructions in to, so there is no need to download.
