@paulschreiber this issue has been there since forever. Reported on it way back. Unfortunately, it's still present.

@mathwizurd Update: turns out it was Google Chrome which was resetting Flux.

I went full screen, clicked on the Flux icon, and saw it was "Disabled for Chrome." I unselected that, and everything worked!

@helloworld234 I'm not sure if this is the bug that's turning Flux, but it seems to have gone away and not come back. I have floaters in my eyes that makes reading tiring and difficult when the screen is bright compared to my office environment, and Flux was a big help until it stopped working. My problem is that Flux has vanished from the bar at top and I can't get it restarted. Any suggestions would be welcome.
Thanks

thanks, that helps me. It was not checked initially, but when I try "Disable->for an hour" it shows me a hidden check-box "Disable->for iphoneSimulator". When I uncheck both - all works as expected.

Assuming you're in the same place at night, I would just dial back the f.lux settings until things look good.

FWIW: personally I do not enable True Tone because I think it is too warm during the day.

Also, I can't find a place to post forum bugs but when I went to enable email notifications it wouldn't let me save due to pagination settings that I assume were the defaults as I did not set them: https://i.ibb.co/KhYBKWF/Screen-Shot-2021-11-09-at-18-14-50.png

Hmm, looks like they are 5 hours behind (or really, 19 hours ahead). But you are right, the language settings should have no impact on local time. I will email for some more debugging.

Thanks - mine is macOS 11.5.2 with Chrome 93, so slightly different, so maybe the Chrome 94 beta is changing some things?

Not exactly related but suggests something is changing:

Which version of macOS is this?

We do all our internals in GMT/UTC so if the sum of time zone and wall-clock time is correct, it should keep working.

Here is a tester script to compare with our server:

So yes, if "UTC time" in the OS is wrong, we will transition at the wrong time.

We only use tz changes as a cue to adjust location (like for traveling between timezones), but cancelling this dialog is just fine too.
