Hi
I am trying to set a flight up here in the UK and under flight conditions, setting the time in daylight hours. Once done I go baclk to the map and choose departure.
Several seconds later the sim resets the time to curent. I have never experienced this befor and am concened as it happens in all regions/countries and all aircraft - any ideas what is going on
FS2020
Quest 3 VR
Similar issue has been reported here for msfs-2024 : Always back to real-time?, the culprit was a 3rd party addon. Have you installed any ?. If so, make sure to disable all of them and test again.
Recently? No
I did install a livery for the FlghtFX 750 though
And also a customer view? Would that affect this do you think
Even if they don’t seem related, when facing an issue within the sim the recommendation is always to disable all addons and test again. If no issue with the base sim (without any addon), then add back one by one your addons to determine which one could be the culprit.
Thank you - it was ELVATEX
Great you’ve identified it !, so it was the same 3rd party application than reported in the other post for msfs-2024 . Happy flights 
Yes. However I am a big fan of ELVATEX and in no way did I change any settings. But it’s resolved and delighted you helped me.
As per @DAQUA3828 there is an option to deactivate time sync, so maybe you can keep using it, playing with that option.
