Default timezone to use in MantisBT. This configuration is normally initialized when installing Mantis. It should be set to one of the values specified in the List of Supported Timezones.

If this config is left blank, the timezone will be initialized by calling function date_default_timezone_get(), which will fall back to UTC if unable to determine the timezone.

Correct configuration of this variable can be confirmed by running the administration checks. Users can override the default timezone under user their preferences.
