DST in the news
by Olson, Arthur David (NIH/NCI) [E] March 12, 2007

March 12, 2007

"Countdown to Confusion: Daylight Saving Time Comes Early This Year, But Will Your Computer Know When to Switch?" appeared on page D1 (front of the business section) of the Saturday, March 3 Washington Post. Prime nugget: "The newsletter of the Los Alamos National Laboratory recently reminded employees to reset clocks on coffeemakers that are programmed to start brewing while the owner is waking up, showering[,] or dressing. The nation's most vital atomic secrets, it seems, should not be entrusted to scientists running low on java. --ado

March madness continues in U.S., Canada, etc.
by Paul Eggert March 6, 2007

March 6, 2007

For the next week or so we can expect to see a lot more publicity about the impending daylight-saving change in the U.S., Canada, etc., which first hits our clocks Sunday (typically at 02:00). Google News currently lists about 1700 news articles on the subject of "daylight saving", and we can expect that number to climb. Nobody has time to read all this stuff, but here are a few selected items, if you care for this sort of thing. (Disclaimer: I contributed to some of them.) Lists of vendor advisories: http://www.calconnect.org/dstlinks.html http://www.reganfamily.ca/dst/ There is now a Wikipedia page just for this event, which contains more vendor advisories (one for the tz database itself!): http://en.wikipedia.org/wiki/Y2K7#Zoneinfo A good summary of Y2K7, suitable for non-techies, is: Steve Lohr, "Time change a 'mini-Y2K in tech terms", New York Times <http://www.nytimes.com/2007/03/05/technology/05daylight.html?em&ex=11733300…> (2007-03-05). Gartner has estimated IT costs between $500 million and $1 billion; see Ben Arnoldy, "Latest computer glitch: daylight saving time", Christian Science Monitor <http://www.csmonitor.com/2007/0307/p02s01-stct.html> (2007-03-07). In an informal poll taken yesterday at a Computerworld IT conference, 52% of respondents said that they were done with upgrading, 39% said they're not done yet, 4% said they hadn't even started (!), and 4% said they didn't know the change was coming (!!). The related story said that Microsoft is still issuing patches. Todd R. Weiss, "Premier 100: Conference attendees deal with daylight-saving time fixes from afar", Computerworld <http://www.computerworld.com/action/article.do?command=viewArticleBasic&art…> (2007-03-06). PG&E, the main utility in northern California, estimated that it'd take $38 million for them to upgrade their meters to account for daylight-saving time. Instead, they got permission from the California Public Utilities Commission to change their billing algorithm during the affected period -- i.e., they changed the rules rather than fixing their clocks. Paul McDougall, "PG&E Says Patching Meters For An Early Daylight-Saving Time Will Cost $38 Million", InformationWeek <http://www.informationweek.com/news/showArticle.jhtml?articleID=197700487> (2007-03-01)

It has been brought to our notice that the DST rules provided in Olsen Time Zone Database and actual DST rules in Brazil for year 2007 and beyond are different. In 2007, as per the Olsen the DST starts on the first Sunday that comes on or after November 1st. However, the actual DST rule states that the DST starts on Oct 21st in 2007. Here are a couple of web sites that show these new DST rules upto 2009. http://www.worldtimezone.com/daylight.html http://www.timeanddate.com/worldclock/timezone.html?n=45&syear=2000 Hence, could you please update the time zone database with the new rules for Brazil in 2007 and beyond at the earliest ?

RE: Microsoft exec says Namibia and Iran have recently changed DSTrules
by Jesper Norgaard Welen March 5, 2007

March 5, 2007

John Gray, thanks for the quick feedback. Concerning problems in 2009 I think that many people loading the timezone updates in 2007 will not do so in 2009 if there were no actual rule changes since - so I recommend getting it right now. Namibia: I must admit I had not seen the -1.00 in Daylight Bias: My first comment is: this will work technically, as you claim! But is it the best way to do it? Actually "hora de verano de Namibia" means "summertime of Namibia", which will apply between April and September. Note that this use of summertime/wintertime is opposite to all other countries (I think) and also to the web links you sent. However, when you look it up in the list, all other countries are also listed for their wintertime, the GMT offset when not applying DST. Putting Windhoek as (GMT+02:00) is therefore a bit like reporting the revenue of 250 companies before tax, and 1 company after tax - it is just impractical for most purposes. Therefore if you want to call the period something different, for instance calling it summertime between April and September, better do the change only in the Abbreviations, so that Time Zone Name is (GMT+01:00) Windhoek, Abbreviation(1) is "Namibia summertime", Offset from GMT is +1:00, Start Day and Last Day are inversed, Daylight Bias is +1:00 and Abbreviation(2) is "Namibia wintertime". This will confuse less people, I think.

From some of their websites, it looks like they simply use "summer time" and "winter time" without referring to either one as a "saving" time per-se. It is also entirely possible different organizations within their government may have different preferences here. >http://www.grnnet.gov.na/News/Archive/2001/March2001/Week4/release_winter_t ime.htm >http://www.grnnet.gov.na/News/Archive/2001/August/Week4/summer.htm >For Chile, yes I am aware we worked hard to get it right. Apparently their official documents defined the change to happen at "24:00" hours, which never actually occurs (I'm not sure if they ever fixed this). A classic case of we know what they meant, but causes us to do strange things in the digital world. >For the rest I'll have to wait for the experts to investigate. >Thanks again, >John Gray >Director, Windows Sustainability Engineering Services
