You can set Last Visit™ to your local timezone by selecting a zone closest to you from the timeszone drop-menu in the settings panel.

NOTICE: This feature will not work on servers which are running in Safe Mode and it will create an error message which says something about it being "unable to set the environmental variable (TZ) in Safe Mode". If this happens to you, simply select Disable/Safe Mode from the timezone select menu in the Last Visit™ settings panel. This will cause Last Visit™ to use the server's own timezone instead of a custom setting.
