Ugh, I forgot how horrible the strftime interface is.
There is no zone information in "struct tm". It gets pulled from the
magic global variable "timezone", and you're supposed to use "tzset" to
set it up. We don't. POSIX says:
Local timezone information is used as though strftime() called
tzset().
but on my system that does not seem to be the case. At any rate, our
options are:
1. Trying to munge a global variable with the timezone information we
have just for the duration of our strftime call.
or
2. Admit that strftime's "%z" is crap, and tell people not to use it.
I think I am leaning towards the latter, though unfortunately I don't
think there is a way to find out the author's timezone via
--date=format, then. Perhaps it should default to "--date=format-local:".
