Here are the patches I promised yesterday for the tz database. They incorporate a lot of changes, the most important of which is for Brazil. In summary: * Brazil has many changes, due to Decree 3,188 (1999-09-30). There is a new Zone, America/Boa_Vista, for Roraima. I also researched older decrees and fine-tuned some transition times to reflect the legal date of change. * Tasmania starts DST early next year for the Olympics, to keep in sync with NSW. (Thanks to Alex Livingston for this info.) * _Nine O'clock_ says Romania used EU rules in fall 1998. For now, assume that Romania and Moldova switched to EU rules in 1997, the same year as Bulgaria. * Kosrae is at UTC+11, not UTC+12. I don't know when they switched to UTC+11. For now, let's assume they switched in 1999. * Tonga's DST switches are at 02:00, not 00:00. (Thanks to Rives McDow for this info.) * A new entry Asia/Dili for East Timor. This will give the tz database at least one Zone for each ISO 3166 country code except for BV and HM, which are currently uninhabited. * The PS country code is now officially blessed by the ISO. FX (metropolitan France) has been removed. HK is still there, contrary to what I thought would happen after Hong Kong reverted to China. * A message in checktab.awk was missing a space. * Makefile sometimes uses awk, and sometimes nawk; it should use $(AWK) uniformly. * The following changes were inspired by the new, 1999 edition of Shanks's International Atlas. - Armenia switched to UTC+4 in fall 1995, not January 1992. - Belarus did not observe DST in 1990. Its DST switches in 1992 were at 00:00, not 02:00. - Most of Australia first used DST 1917-01-01 00:01, not 1916-10-01 02:00 which applied only to Tasmania. - Lord Howe Island changed its fallback rules from the 3rd to the 1st Sunday in March in 1992, not 1990. - Jamaica switched to US rules on 1974-04-28, not 1974-01-06. - Kirgizstan's 1991-08-31 transition was at 02:00, not 00:00. - Libya did not observe DST in 1990 or 1996. Instead, it switched from CET to EET in spring 1990, and then back to CET in fall 1996. - In Mexico, Ensenada has never differed from Tijuana, so it shouldn't get its own database entry. Baja California started using US rules in 1976, not 1967. - Mongolia's fall 1996 transition was on 10-27, not 10-25. - Paraguay switches the last Sunday in February, not the last Saturday, contra to what the IATA says. There were also some changes for older transitions. - Syria's spring transitions in 1997 and 1998 were the last Monday in March, not April 1. - Tajikistan stopped using DST on 02:00 the day they declared independence; they did not wait until 20 days later. - Uzbekistan observed DST in 1991. - Asia/Jakarta switched to UTC+7:20 12 minutes and 48 seconds before 1924-01-01 00:00:00 local time, not 13 minutes after. This corrects an obvious typo in Shanks (1999) that I discovered while entering data for Dili. I found and fixed similar errors for Mexico, Costa Rica, and Cuba. - Several other minor changes to commentary, mostly reflecting corrections embodied in Shanks's latest version. diff -pru tz-1999gh/Makefile tz/Makefile --- tz-1999gh/Makefile Tue Sep 28 15:06:18 1999 +++ tz/Makefile Fri Oct 8 20:52:03 1999 @@ -358,12 +358,12 @@ public: $(ENCHILADA) zic -mkdir /tmp/,tzpublic for i in $(TDATA) ; do zic -d /tmp/,tzpublic $$i ; done rm -f -r /tmp/,tzpublic - nawk -f checktab.awk $(PRIMARY_YDATA) + $(AWK) -f checktab.awk $(PRIMARY_YDATA) tar cf - $(DOCS) $(SOURCES) $(MISC) | gzip -9 > tzcode.tar.gz tar cf - $(DATA) | gzip -9 > tzdata.tar.gz zonenames: $(TDATA) - @awk '/^Zone/ { print $$2 } /^Link/ { print $$3 }' $(TDATA) + @$(AWK) '/^Zone/ { print $$2 } /^Link/ { print $$3 }' $(TDATA) asctime.o: private.h tzfile.h date.o: private.h diff -pru tz-1999gh/africa tz/africa --- tz-1999gh/africa Tue Sep 28 14:42:06 1999 +++ tz/africa Sat Oct 30 06:27:18 1999 @@ -7,8 +7,8 @@ # From Paul Eggert <eggert@twinsun.com> (1999-03-22): # # A good source for time zone historical data outside the U.S. is -# Thomas G.
