Describe the issue you are experiencing

I have my browser set to not provide time zone information to websites I'm visiting, as an anti-fingerprinting measure. As such, Home Assistant thinks that I'm in UTC time instead of the timezone that I'm actually in. I accept this, and to work around it, I set the Time Zone setting to "Use server time zone".

This works fine in most areas, but when I go to the history screen and use the date/time selector, the times listed are in the wrong timezone. The history that gets displayed shows with the correct times, and the dates/times shown in the "Start date" and "End date" boxes are correct. However, the times shown in the drop-down time selectors are not.

Describe the behavior you expected

The selector should select time using the timezone of the server when the time zone setting is set to "Use server time zone"

Steps to reproduce the issue

1. Set your system timezone to one that's different than the server time, or set your browser to not provide timezone information to the server.
2. Go to the profile settings, and in the "Time Zone" setting, select "User server time zone".
3. Go to the history page.
4. Select at least one entity to display history for.
5. Expand the date/time picker.
6. Note that the times displayed in the "Start date" and "End date" boxes do not match the times selected in the drop-down time selection boxes.

Additional information

The way I'm doing the "resist fingerprinting" by going to about:config and setting "privacy.resistFingerprinting" to "true", but a more granular approach can likely be taken for testing by only setting "privacy.resistFingerprinting.testing.setTZtoUTC" to "true".

Just giving this a bump since it's 2 weeks old and I don't want it getting marked as stale. I'm running into this issue as well.

Still present in 2023.12.* when using the server timezone setting. Fingerprinting seems unrelated

Thanks Thomas. The time/date pickers are still not respecting the profile "Use Server Time Zone" setting.
