For timestamps in the past "absolute" time is almost always known, so 
beside timezone identifiers like Australia/Sydney it is possible to use 
UTC or fixed offset 2023-01-21 Sat 05:55:54 -1000. If a timestamp in 
future is bound to specific timezone then its identifier must be used 
since the government may change time offset. Of course there are cases 
when UTC or timestamps with fixed offsets are used as well: e.g. Lunar 
eclipse or participants with multiple locations are expected.

So it is "feature" of some timestamps in future that attempt to store 
them in UTC may lead to their invalidation later.

Is the following timestamp is in user local timezone or in UTC?

<2023-02-01 Wed 15:00>

If features like the following is implemented then it will not be in 
local time zone:
- file-local
   #+TIMEZONE: UTC
   or
   #+TIMEZONE: Australia/Sydney
- subtree-local
   * H1
   :PROPERTIES:
   :TIMEZONE: Australia/Sydney
   :END:

So looking at such timestamp it would be hard to choose particular case 
from the set you proposed.

Of course it leads to tricky cases when some timestamp is copied to a 
scope with another time zone. It requires some yank handler and text 
properties. When timezone is added to a subtree, perhaps, all timestamps
inside may need to be changed from implicit timezone.

For storage format I would use another types
- explicit/implicit time zone
- Specific timezone/fixed offset. UTC and Etc/GMT-11 zones are identical 
to +0000 and +1100 offsets accordingly.

For UI it is better to choose some terms to make the manual and UI 
dialogues more clear.

I am not a native English speaker and terms "event", "occurrence" sounds 
confusing for me. E.g. a conference is an event. A regular meeting (even 
when scheduled in another time zone) or "brush teeth" are more close to 
occurrence. As soon as you have to split "event" category into 2 parts 
perhaps it is better to pick 3 different names. I may ask for fourth 
that is absolute, but not UTC, but I would prefer to not insist on 
namely UTC and use fixed offset instead.

For UI it is meaningful to name
- default time zone for this scope (with a hint if it is currently 
system-wide, file-local, or specific to subtree), so no explicit 
timezone will be set.
- absolute (UTC or fixed offset) preferred for global event
- bound to location (e.g. Australia/Sydney)
- ad-hoc timezone that follows user in their trips (close to Ramsey's 
"occurrence").

The problem is to push users to timezone identifiers for future 
timestamps associated with some location. Offsets must be discouraged 
this case, but encouraged for on-line meetings. For past timestamps 
particular choice is less important. That is why I separated future/past 
timestamps.

Unsure it it may be implemented reliably.

libc has a concept of timezone. I think, it should be the primary 
source. It is initialized on application startup (roughly) from 
system-wide settings, may be overridden by TZ environment and changed 
later by setting another value of TZ. The problem is that identifier 
like "Australia/Sydney" is considered implementation specific and is not 
directly accessible from the code, it is sealed inside the library. 
Another issue is that I do not know if Emacs is able to receive 
notifications on change of system-wide timezone.

Web-application may request time zone settings from the browser:
     new Intl.DateTimeFormat().resolvedOptions().timeZone

Android devices may have outdated and incomplete zoneinfo database. This 
case either computations should be performed on the server or tzdata 
copy should be bundled into the app.

Client-server application may use resources maintained on servers, emacs 
must be able to run off-line and enough user will be unhappy noticed 
some outgoing queries.

Ubuntu installer or e.g. Google relies on GeoIP databases.

Geodata for timezones is available, but laptops or desktops mostly do 
not have GPS receivers. IP behind NAT is not useful to determine location.

It is possible to make GeoIP database (quality of ones available for 
free are not high) and map of timezones, but I do not think it is 
reasonable.

I suppose, system timezone would be enough for Org. Third party packages 
might implement another way.
