Wrong time shown in games running through Proton

All games I play through Proton show the wrong time in game. This didn’t matter for a while, but has been a bit annoying since Deadlock released with the set queue times it had. Is anyone else having this issue? I never had it on Distros I used before. I can’t even remember if it always happened on NixOS or if it’s a recent thing…

Missed that in my searching somehow. Thanks!
