I've just installed FSX on a new system after years of using FS9.  There's a problem with the time and I can't figure it out.

 

I'm on the east coast of the U.S., -5 hours GMT.  The default "Friday Harbor" shows the current and correct time for here in the eastern time zone.  However, when I go to KATL, KJFK, etc., the time changes +3 hours.  In other words, 12 noon real time becomes 3pm.

 

This three hour shift forward has me baffled.  Any help would be appreciated.

 

BTW, my computer time is accurate and is set to the right time zone.

 

Thanks!

I think if you change your location to your local aiprot.. then Save the Flight.. making it your default flight.. next time you open FSX.. your time will be your time, like before, but now it considers you in EST time zone..

"Time" in FSX has what I call a setup phase and a run phase.  In setup phase, FSX takes a local time, either from your system or from the saved flight which you load.  It then applies a timezone correction based on the location of your aircraft to determine GMT/UTC.  That completes the setup.

 

In run phase, FSX maintains the GMT/UTC and applies the timezone correction at current aircraft location to compute local time.

 

Note that the timezone corrections are based on an internal timezone model that is modified by timezone scenery files (default FSX provides one for the US and western Europe with daylight savings as in effect in 2006).

 

So what you see is the local time is set at Friday Harbor (12M).  Timezone correction is applied for that location (-8) and GMT is computed as 2000 (8:00PM).  That's the setup.  Now you move your aircraft to KATL.  GMT is still 2000.  The timezone for KATL is -5 and that correction is applied, so local time is 1500 (3:00PM).

 

If your default or saved flight is in your timezone, then during setup GMT will determined and match real-world.  Otherwise you must change time so GMT is real-world, or use an addon such as FSRealtime which forces GMT into FSX for you.
