I have been informed that GNU strftime() implements this same behaviour,
using %z in the same way. My only available reference is an old Debian
box which does not document this. I have not examined the code. This
is a clean-room implementation.
Thinking about -0000 ("not telling you my timezone") - I seem to recall
that there was a struct tm entry which could be used for this. An old
fuzzy memory suggests tm_isdst, but this is not documented on FreeBSD
strftime(3). strftime.c has %Z giving '?' if tm_isdst is not either 0
or 1 - my memory suggests -1. This would have been either Solaris or
GNU, from documentation read some time ago. If an definitive answer for
this can be given, the code mod is trivial.
A feature request (already!) is to support +nn:nn which allegedly the
GNU version can't handle. Could someone with appropriate authority
please say if it is acceptable to use %Ez? I suspect not. :^/
