Here are some proposed patches that are in addition to the patch circulated earlier today by Arthur David Olson. * Lots of changes for Nunavut, brought to my attention by Antoine Leca and Rives McDow (though I made several further changes). - Pangnirtung is now on Eastern Time. I wildly guessed a switch in 1995. - Nunavut converts to Central Time on October 31. This entails a new Zone, America/Cambridge_Bay. - I found a claim that Coral Harbour, Nunavut, does not observe DST, but I vaguely recall that Canadian law does not permit this, so for now I left that as a comment only. * Palestine no longer uses the same DST rules as Jordan (if it ever did). Add a separate rule set for Palestine, with my best current guess for what this year's rules are. * Revert to the abbreviation `EEST' during summer in Bulgaria. I think the Bulgarian document (or translator) was mistaken when it had `EETDST'. * Add commentary from Joseph S. Myers about `BDST', and about Channel Islands summer time during World War I. * Clarify which states are affected by recent decrees in Brazil. * Shorten the comments about Jordan. * Modify tzselect.ksh so that it explains its output better to the casual user. diff -pu tz-1999ee-patch/asia tz/asia --- tz-1999ee-patch/asia Mon Sep 20 16:15:18 1999 +++ tz/asia Mon Sep 20 22:57:37 1999 @@ -648,28 +648,14 @@ Zone Asia/Tokyo 9:18:59 - LMT 1887 Dec 3 # Since 1938, all Japanese possessions have been like Asia/Tokyo. # Jordan -# From Steffen Thorsen [straen@thorsen.priv.no] (1999-05-08): -# Jordan do not have DST this year.
