Brazil timezone changes for Oct1999 and Feb 2000 and a question
by Marcus Chase Oct. 20, 1999

Oct. 20, 1999

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

Time Zones for Cities (argh)
by Rich Shockney Oct. 15, 1999

Oct. 15, 1999

The subject of determining the correct time zone for any city has come up before in this forum. I am interested in pursuing whether some city -> time zone mapping might be possible, but wanted to get the opinions of others here before heading down the wrong path. So, a couple of questions: (1) Has anyone successfully done this? I realize that trying to maintain this mapping manually introduces a technique that will most likely be error-prone. (2) The tz database lists a long/lat for each time zone. If I know the long/lat for a particular location anywhere in the world, is it possible to accurately interpolate the time zone given this information in the database? If so, does anyone know of a good source for long/lat data for major/minor cities? Is this even possible to achieve? Is there a better way? And, I'm only interested in current time/time zone mapping and not worried about historical data, in case that might make the task any easier. Thanks. Rich Shockney

FW: Tasmania to start DS with NSW etc. in 2000
by Olson, Arthur David (NCI) Oct. 8, 1999

Oct. 8, 1999

-----Original Message----- From: Alex LIVINGSTON [SMTP:alex@agsm.edu.au] Sent: Monday, October 04, 1999 8:38 PM To: tz(a)elsie.nci.nih.gov Subject: Tasmania to start DS with NSW etc. in 2000 I heard on the ABC (Australian Broadcasting Corporation) radio news on the (long) weekend that Tasmania, which usually goes its own way in this regard, has decided to join with most of NSW, the ACT, and most of Victoria (Australia) and start daylight saving on the last Sunday in August in 2000 instead of the first Sunday in October. Would someone else like to look around for written confirmation of this? --Alex
