Recent enough versions of zic don't issue that warning. If you wanted
to put such an abbreviation in a POSIX-style TZ environment variable
value, it would need to be placed in angle brackets like this:
TZ='<+07>-7'
(which, admittedly, looks a little odd, but that's the fault of UNIX
tradition).

zone is from UTC!
