When I load up FSX, the time and date is always in sync with my system because I have "Use system time for free flight" checked and also in FSUIPC I have a similar option as this one enabled. So when you load a free flight this all works fine, but when you load your saved flight back up, this doesn't work. It only puts the system time in sync, but not the system date. Lately I noticed the date in FSX was like 2 weeks behind on the actual date. I only use saved flights every time so that is why. 

But does anyone know how to make FSX select the date automatically even when loading up a saved flight? The reason this bothers me is because of seasonal textures.

Try software fs real time.

The date you saved the flight is saved as part of the data. You could open the saved flight data and edit it before loading the flight. Or, load the flight in FS and adjust the date accordingly.

fsuipc documentation suggests it might be possible to set the Day-of-Year into offset 0x023E.  Also Lua reference suggests that standard library function os.data("%j") might return the Day-of-Year as string.  If so a Lua program along the lines of

 

ipc.writeUW(0x023E,os.data("%j"))

 

might accomplish what you want.  You would set it to run at startup.

Oops! just realized I had a brain fart, should be os.date not os.data.  Corrected below:
