Incoming emails are dated 1 hour ahead of the current time. The headers are correct and the time in the preview pane is correct.

New appointments are created 1 hour behind the current time. If I create an event on my Pixel XL it syncs to Thunderbird at the correct time.

I found this topic that seems to mirror mine but I have absolutely no idea what the "solution" is. https://support.mozilla.org/en-US/questions/1229111

My time zone is correct in Options but there is no selection for Daylight Savings Time on or off. Arizona does NOT use DST. That would explain the one hour ahead of emails but not the one hour behind on events in the calendar.

I've been running Thunderbird for years and this is a new issue within the last few weeks.

I'm on a Win10 Dell laptop running 60.8.0 and am told it is up to date and I am on the release update channel.

Thoughts?

Did you exit Thunderbird first Then set: turned off auto time zone and set it to UTC -7 Arizona Then restart Thunderbird

Although the problem sounds the same, the topic link you mention is not the same because you are not using a Linux OS.

Thunderbird uses the Date/Time/Timezone settings on your computer. Please double check all is correct. In Windows Search type: Date and select 'Date and time settings'

re :Arizona does NOT use DST General info: https://www.timeanddate.com/time/zone/usa/arizona

I've got Win10 and noticed there are two settings which you may/maynot be using. Time zone: I see a 'UTC Mountain Time' which auto sets an adjustment for DST, but I also see 'UTC Arizona' which does not auto set DST. Which one are you using? Is it the correct one? Is daylight saving time switched on or off?

Previously I'd gotten screwy results when I let the computer figure it out itself so I was on:

Set time automatically ON Set time zone automatically OFF Time zone UTC -7 Mountain Time Zone DST OFF

I just changed it to automatically set the time zone and nothing changed.

I then turned off auto time zone and set it to UTC -7 Arizona and nothing changed.

Of course not... why would that work when setting my laptop to the correct time zone and DST settings doesn't work :)

After a restart everything appears to be working properly

Isn't it lovely that Arizona time is EXACTLY the same time as the Mountain Time Zone without DST yet either or both Windows & Thunderbird don't get it?

Thanks!
