Follow these instructions to manually create the new time zone:

To help you automate this process, a script follows for the Windows NT resource kit tool, 'Regini.exe'. You must customize the key name and the values for your installation. Please note that the bytes in the 'REGINI'-script are ordered differently than shown by the Registry Editor. After you run the script, repeat step three as previously shown.
