This shows whatever time the people created the meeting, but everywhere else we've moved to showing the time in UTC by default and using JS to show options (utc, local, meeting time). This view should do the same.

We should also put the date and time on the group meetings page.
For future and in-progress sessions, the time should show here somewhere:

Thank you for continuing to improve things for meeting participants.

I think we need a few more touches before merging this -

at http://localhost:8000/meeting/interim-2023-cbor-16/session/cbor I see:

It would be good to put the timezone selectors there as well (instead of the current showing of timezone declared for the meeting), again with default to local (?).

At http://localhost:8000/doc/agenda-interim-2023-cbor-16-cbor-01/ I see:

The time happens to be in Local (I think) but the Local cell is not selected so it's not clear what the timezone is until clicking around a bit.

Also, when the Meeting option is pressed, the result is:

which says nothing about what timezone that actually is?

@rjsparks last commit should fix your issues. I couldn't reproduce "Local cell is not selected", it is selected in my dev instance. (Did you yarn legacy:build?)
