+$! east of UTC (formerly known as GMT).  Sample values: -300 (US east coast),
+$! -480 (US west coast), 540 (Japan), 60 (western Europe).
+$!  VAX C's HELP information says that you should be able to use gmtime(), but
+$! it returns 0 for the struct.  ftime(), you ask?  It, too, returns 0 for a
+$! timezone.  Nothing sucks like a VAX!
