please, report on current status of orgmode timestamps with timezone

[pinmacs <pinmacs@cas.cat>]

Hi,

 From #11 OrgMeetup content [1] I see that a date with timestamp and 
timezone is used:

     <2024-09-11 Wed 19:00-21:00 @+03,Europe/Istanbul>

With orgmode version 9.7.10:

1. If I try to to =C-c C-c= minibuffer says: "Not at a timestamp"; well, 
at least, does not try to remove the timezone part
2. Cannot change anything on it with =S-<up>= nor =S-<down>=
3. If I click the timestamp, minibuffer says: "This should not happen"
4. In the org agenda, the event appears in date 2024-09-11 and in my 
local time 19:00-21:00, so, no timezone calculation is done

I saw that there were some discussions about this, but nothing 
consolidated in the documentation, maybe, at some point, it should be 
here [2]

Is this something is going to arrive on 9.8 ? Is this something that 
only works in development version?

Cheers,
pinmacs
