tztab changes for HPUX

[Arthur David Olson]

Current versions of the public-domain time zone package
do the right thing for October, 1995:

	Script started on Mon Feb 12 10:53:47 1996
	elsie$ ./zdump -v Europe/London | grep 1995
	Europe/London  Sun Mar 26 00:59:59 1995 GMT = Sun Mar 26 00:59:59 1995 GMT isdst=0
	Europe/London  Sun Mar 26 01:00:00 1995 GMT = Sun Mar 26 02:00:00 1995 BST isdst=1
	Europe/London  Sun Oct 22 00:59:59 1995 GMT = Sun Oct 22 01:59:59 1995 BST isdst=1
	Europe/London  Sun Oct 22 01:00:00 1995 GMT = Sun Oct 22 01:00:00 1995 GMT isdst=0
	elsie$ exit

	script done on Mon Feb 12 10:54:36 1996

Howmsoever...the references to and excerpts from "tztab" files in the articles
about HPUX indicate the existence of an alternate and (presumably better) way
of handling time zone stuff. If anyone has tztab insights to share with folks
on the list, I'd love it.
