The bit about %Z is
%Z is replaced by the locale's time zone name or
abbreviation, or by no characters if no time zone is
determinable. [tm_isdst]
which I suppose is because struct tm is speced without tm_zone.

You'd think a system with tm_zone should use it, but yes no sense
demanding what doesn't work.

Since we initialize tm_zone if it exists we should be safe, but a note
in the docs about what guile tm:zone might or might not do could be in
order.
