When did Pitcairn switch its time zone?
by Paul Eggert Nov. 8, 1999

Nov. 8, 1999

A public-domain time zone database <ftp://elsie.nci.nih.gov/pub/> maintained at the US National Institutes of Health attempts to keep track of all the time zones in the world, along with the history of exactly when each location changed from one time zone to another. Currently it lists Pitcairn as consistently being 8.5 hours ahead of Greenwich since 1901, but Mark Brader recently reported that the 1997 UK Hydrographic Office time zone map lists Pitcairn as being 9 hours ahead of Greenwich, and the 1997 CIA time zone map agrees. Is this correct? Do you happen to know when the switch occurred (ideally, the date and time), or know who might know? Any info that you can give would be helpful in correcting the time zone database. Thanks.

proposed tz fix for Brazil, Tasmania, Romania, Kosrae, Tonga, etc.
by Paul Eggert Nov. 4, 1999

Nov. 4, 1999

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(a)twinsun.com> (1999-03-22): # # A good source for time zone historical data outside the U.S. is -# Thomas G.

Hello Timezone, Brazil/East time changes for Oct1999 and feb 2000 occured for Rule Brazil 1999 only - Oct Sun>=1 0:00 1 D Rule Brazil 2000 only - Feb Sun>=26 0:00 0 S The time is not certain. I have yet to see a governement rule that firmly states at what specific hour to time change is to occur. We have TZ=Brazil/East. The original southamerica file on our system had "Rule Brazil 1988 max - Oct Sun>=15 0:00 1 D" In late September I changed max to only for the 1988 rule and added the 1999 and 2000 rules. But my system only changed to EDT on Sun the 17th of October. I ran ´truss -a -f -wall -vall -rall date´, which revealed that date opens /usr/share/lib/zoneinfo/Brazil/East, but does not open southamerica. After updating the southamerica file do I have to ´rebuild´ the Brazil/East file in some way? Attached is my southamerica file. Cheers, Marcus Chase
