I see.  Indochina is a word i would be careful with myself, but
i am sure they all know.

I could give this a try.

I always learn, and i like learning; if i read

  <"$f" || {

i would never have tried on my own, maybe "<X :", but not without.
And the main loop has a tremendous compound-list-1, and a very
short compount-list-2.
So hard to believe an outsider without real insight can make an
acceptable improvement here without hm work.  I think the change
likely should be as local as possible, maybe around "Get list of
timezones in the country."

...

So i tried and have a hacky thing that shows what i mean "a little
bit"; if we try Asia->Laos with -t zone and without, it shows "the
other zonetype" context.  But it surely can be improved.

Regarding data cuts: isn't it enough to document it as it is done
in the patch 0002?  Otherwise more context data would have to be
placed all around, so that the shell script could say something
along the lines "warning, pre-1970 clock times mismatch chosen TZ
identifier", that is, when i choose Asia/Vientiane via -t zone (as
with the 1970-01-01 cut-off those times are _indeed_
Asia/Bangkok)?
