"FS Real Time" has been designed to keep Microsoft® Flight Simulators UTC (Zulu/GMT) time and date in sync with the Real World. You can have it maintain either the current Real Time, or an offset (+/-) so you can fly at any variation of time from the Real Time. This program will monitor your aircraft's current UTC offset.
