Thanks for the pointer [1].

Yes, Org is a bit scared to touch time format, and in a way, I do
understand that.

I'm unhappy myself with Org timestamps, but given how conflict-laden
the topic is, I opted for keeping my local hacks and dealing with
some fallout on version changes. Not optimal, but I haven't better
ideas myself currently.

I don't understand what you mean by "the tz database format" in this
context. What I meant is the '%z' information (e.g. -0400) instead
of (or in addition to) the '%Z' one (e.g. EDT), in the sense of
`format-time-string'.

But perhaps we mean the same.

Yes, I get the "design tension" there. I don't have better ideas.
A greater flexibility in timestamp representation would have seduced
me; a file-global setting... not so much.

Still, I wish you good luck :-)

[1] BTW I hate SX. Theycl've come up with yet another of those cookie
   tortures to take revenge on the users for some mild privacy protection
   laws. Of course I don't want any cookies. You @#&$s don't even have
   to ask: you @#*&%$ can infer that from the fact that my browser doesn't
   accept cookies in the first place!  You so-called web programmers
   manage to elicit feelings in me I'm less-than-proud of.
