It returns "EST" or whatever the current time zone is.

The problem is that `struct tm' doesn't have any time zone fields on
Solaris, so it's difficult for scm_strftime to control what strftime
will emit for %Z.

I think there used to be code in there to temporarily set the "TZ"
environment variable, but that was always a hack-and-a-half.  I'd
rather simply say "We don't support this on all systems" than do that.
