I'm temporarily in Los Angeles. So I changed the time zone setting for TB. But when I did that it seemed to change the times for all my previous calendar events, which were created in the Eastern Time Zone. I don't think that should happen.

Am I doing something wrong?

To change the time zone, you need to change the time zone of the system.  There is no separate time zone in Thunderbird or Firefox.

Now when you change the time zone of the system, your calendar times will change relative to the time zone at the time.  When you revert to your original time zone things will return to what it was when you set them up.

Does this help?

I have changed the timezone of the system. So, e.g., my TB mail shows the correct local time for mail I send out.

But there's also a separate time zone setting for the calendar under Edit-Preferences-Calendar-General. That's the one I reset. When I do that, all my previous calendar entries, made in the eastern time zone, have their time changed, so the calendar is telling me I did something at 4am when I actually did it at 7am. I may be in the pacific time zone now, but I wasn't when I did that event at 7am. So it shouldn't be saying the event took place at 4am.

(Running Fedora 24 and TB 45.8.0, which is up-to-date for Fedora 24.)

Yes, you changed the time zone.

If the calendar is merely restating Eastern Times as Pacific Times (eg
8am Eastern --> 5am Pacific), because presumably you want to sync your
LA actions to the Eastern Time events, that shouldn't be a problem.

If the times are restated incorrectly, then the programmers were
confused about time zones. Use a better calendar.

Enjoy the sun.

As I said in my previous post, all times in your calendar are now
Pacific. So whatever you did at 7am Eastern, you did at 4am Pacific.
Perfectly logical, and essential for any future events (else you may
forget to adjust and make a phone call home 3 hours too late, for example).

Sidebar: When Sanford Fleming proposed worldwide Standard Time, he
planned a single universal time, so that 12:00 would be 12:00 everywhere
on Earth. But that would be lunch-time in London, and breakfast time in
New York. Since everybody though of 12:00 as noon wherever they were,
his plan was ditched. Hence your calendar problem.

I see your point. When I'm in l.a. I don't want to have to remember that I made the 9:00 apt while in NYC. I need to know it's at 6 my time.
