Where location also includes time, sometimes (think DSTs). IMO, a timezone
is nice for added context, but meaningless without a concrete offset wrt
some agreed upon base (UTC, here on Earth, for example). Unless you use
clearly different shorthands (e.g. CST for Central Standard Time [1]
and CDT for Central Daylight Time).
The nice cherry on top of that is that this context info is sometimes
relevant and sometimes not. A regular appointment ("brush teeth") may
want to be seen relative to the current time zone (so it "moves" when
I travel from Berlin to New York), another ("Jitsi meeting with my
colleagues in Delhi, Dar-Es-Salam and Denpasar") might not.
I warmly recommend the Wikipedia page [2] on that topic.
An interesting problem :)
Cheers
[1] Eh. Nevermind that it also can mean Cuba Standard Time or China
Standard Time.
