Following on from thread at
https://www.reddit.com/r/orgmode/comments/zrppqw/

[First off, I just wanted to say thank you to everyone that works on
org-mode. It is a wonder.]

While I realize a few kicks at this can may have been taken, I wanted to
(re-)propose Timezone support in org-mode. The world is much less local
these days and we're all more remote and coordinating globally these days.

*Background*

1. org-time-stamp-formats TZ currently only affects display and exports
2. org-agenda itself is not TZ aware
3. Several discussions on this have taken place over time
4. Concerns raise included breaking backwards compatibility

*Proposal*

1. org-mode sets an optional variable (org-timezone-aware t) which enables
TZ
2. org-agenda needs a way to determine which timezone it is in
3. Once enabled, any timestamp not exhibiting a TZ in it is considered
"local time" wherever that is (I do not think UTC would work for this)
4. org-agenda can calc local based on TZ differences

I understand this is by no means trivial and quite gnarly with DST and such
to figure out but I do believe libs exists to deal with that heavy lifting.
Currently, it does feel like a hole in org-mode as a 21st century organizer
(disclaimer: digital nomading so might feel it more keenly). Also, just
interested in making org-mode a more awesome tool for everybody.

I'd love an understanding of the alluded to reservations raised in the
reddit thread and in the mailing list threads mentioned that the format
change might break things (I was unsure if that was referring to say, how
time ranges were handled, or how say date ranges got dealt with (for
example, say a flight from Singapore to Vancouver which takes off in one
time zone and lands in another - something that is often in my cal.).

thanks!
Daryl.

Great link!
https://spin.atomicobject.com/2016/07/06/time-zones-offsets/

"Given a local time and an offset, you can know UTC time, but you do not know which time zone you’re in (because multiple timezones have the same offset)."

So, given a time zone you can know the offset (Google it, for example)..
Then, given the time zone and the local time, you can know UTC.
If orgmode gets the UTC there is not ambiguity.

But, that would mean that the offset related to the different time zones must be downloaded and updated from some site.
As you said before, that offset can change. For example, peninsular Spain has the same time as Berlin, but as this doesn't make much sense, it could change, so updates would be necessary.

I have been thinking about how I would use this feature. So use cases 
appeared, which arose some doubts about how to use this feature, and an 
opinion for the Poll surged:

If I wanted to assist to a "Mastering Emacs book club" meeting in 
America/Vancouver, while living in Spain: Doubt: Should I use local time 
of America/Vancouver to schedule the meeting?. Like: [2024-02-04 12:00 
@America/Vancouver] (I don't like space before the @, for the Poll).
1. Doubt: I suppose my agenda timestamp would be: [2024-02-04 do. 
21:00]. (Spain local time). Correct?
2. If I went on vacation to Brasília, my agenda timestamp should change 
to: [2024-02-04 do. 17:00]. (Brasília local time).
    Doubt: How must the local time zone be updated to get that timestamp 
changed?
3. Back to Spain, I see that, for political reasons, Vancouver's winter 
time-zone changed from UTC-8 to UTC-9.
    Doubt: How would my tz database be updated?
    Doubt: After updating the tz database, my agenda timestamp would 
change automatically to  [2024-02-04 do. 22:00]. Correct?
4. For the Poll: What would be the expected behavior if we used the UTC 
offset?  [2024-02-04 12:00 @-08,America/Vancouver]
     - We should know beforehand the DST of Vancouver, or there would be 
warnings. It seems more difficult for the user: maybe the "-08," should 
be optional?
     - Case 3: After updating the tz database we would get warnings too. 
To correct those warnings, should the UTC offset be changed manually in 
the timestamp?. If there were 35 meetings in Vancouver throughout the 
year, to change all the UTC offsets could be non trivial for a normal 
user: UTC of the summer and winter would differ.
       [2024-09-04 12:00 @-07,America/Vancouver] should be changed to 
[2024-09-04 12:00 @-08,America/Vancouver]
       [2024-02-04 12:00 @-08,America/Vancouver] should be changed to 
[2024-02-04 12:00 @-09,America/Vancouver]

Could it be reasonable to collect the hypothetical cases where relative 
timestamps would be used?
So, alternatives and solutions could be evaluated more easily.
For example:


| External Input                                          | User's 
input                     | Org output                             | 
Agenda output (local time) | Org time storing     |

|---------------------------------------------------------+----------------------------------+----------------------------------------+----------------------------+----------------------|
| Meeting at 09:37:54, 28 February 2023, in Foz do Iguaçu | [2023-02-28 
ma. 09:37 @UTC-3]    | [2023-02-28 ma. 09:37 @UTC-3]          | 
[2023-02-28 ma. 13:37]     | 20230228T12:37:54,68 |
| Same case as above                                      | [2023-02-28 
ma. 09:37 @timezone] | [2023-02-28 ma. 09:37 @UTC-3,timezone] | 
[2023-02-28 ma. 13:37]     | 20230228T12:37:54,68 |
| Party at my home, tomorrow                              | [2023-02-13 
lu. 14:15]           | [2023-02-13 lu. 14:15 @UTC+1,timezone] | 
[2023-02-13 lu. 14:15]     | 20230213T13:15:54,68 |


- I didn't expect this: it is more difficult for me to find the 
timezone, and to write it in the correct format, than to find the UTC 
offset.

- Maybe org output should always show the time zone, since for calculations

- Should convert show every timestamp timezone, so we know local 
timezone is correct?

- Sorry for the table format, I don't know how to export it from orgmode 
to thunderbird's mail editor.
