I just now updated <http://www.twinsun.com/tz/tz-link.htm> to point to that page. I noticed one other minor problem with that web page: it mishandles zones whose names contain two or more slashes. For example, the web page has an entry 'Indiana' but when I follow the link to the URL <http://twiki.org/cgi-bin/xtra/t?tz=America/Indiana> the resulting web page says "Invalid Timezone: America/Indiana -- /usr/share/zoneinfo/America/Indiana". The affected zones are: America/Indiana/Knox America/Indiana/Marengo America/Indiana/Vevay America/Kentucky/Monticello America/North_Dakota/Center I see the web page doesn't list any name related to America/North_Dakota/Center, which was added in tz-2001d. Nor does it list other recently-added names like America/Bahia (added in tz-2003d). Perhaps you're using a old version of the tz data, or an old version of the tz names? You can get the current list of names from zone.tab in the tz distribution. This suggests another possible improvement: at the bottom of the web page you might list the tz version number or some other time stamp associated with the tz table itself. Unfortunately there's no easy way to get the tz version number from the installed data. These are common-enough problems that I'll CC: this to the tz list.
