sometimes i arrive to destination a hour early or an hour laterbut gmt times correctlocal times are not working appropriately somewherewhat is wrong with fs2004 i don t know

It's been a know bug since FS2004 was released!There are many applications that will correct this, Search for World Time Zones.Or use a time synch program like Fs Realtime, That will fix your problem.

I recently had the same problem , cured it by - Start FS9, goto General Settings, click Flight Time, exit FS9, re-start FS9, goto General Settings, click System Time, exit FS9 and re-start. This cured it , my default flight time is U.K. when I change say to New York I automatically get the New York time. Hope it works for youEchofox

I use FS Realtime too, works very well.Steve.
