File format
by Philip Warner Nov. 28, 2006

Nov. 28, 2006

Another silly question, but is the format of the zone text files (eg. australasia etc) documented somewhere...I have a quick look in the files themselves, but could not find much....apologies if the answer is obvious, but I've looked in several files.

Suggestions about separation and ISO code
by Jonas Melian Nov. 27, 2006

Nov. 27, 2006

Some suggestions: 1) To using ISO 3166 3-character country code becasuse is more readable. http://en.wikipedia.org/wiki/ISO_3166-1 For any person it's easier to identify a country by the code of 3-letters that by the one of 2-letters. 2) Columns separated by another character different of a tab, as ':'. So it's more readable for humans and too for the machines. And so it's easier to maintain that table. I comment you these suggestions because I have something of experience with this type of tables as you can see here: http://webda.python-hosting.com/browser/trunk/data Greetings!

Updated timezone info for Western Australia DST trial
by Mark Glossop Nov. 27, 2006

Nov. 27, 2006

Hello, I've recently been tasked with managing the update of our Unix machines to cope with the recently announced (re)introduction of DST in Western Australia - yes, we've been given less than 2 weeks to prepare for the start of the trial period this year :-( Please find attached a copy of the updated "australasia" file that contains the appropriate modifications (it's based on the 2006o timezone information.) Feel free to contact me with any questions or clarifications - I've tested this file as best I can but would not be surprised if more experienced eyes see problems with it. Best regards, Mark -- Mark Glossop Systems Administrator FAHSS Faculty Computing, UWA E: Mark.Glossop(a)uwa.edu.au P: +61 8 6488 2092 M: +61 4 0028 3252 IM: theonlycueball(a)mac.com (AIM)

Daylight savings time change in Western Australia
by Benno Rice Nov. 24, 2006

Nov. 24, 2006

Western Australia is trialling daylight savings for the next three years. They're planning to switch in on December 3 and then follow the same sort of rules as most of the other Australian states that use DST. The attached diff should implement this, at least for the trial period. -- Benno Rice benno(a)jeamland.net http://jeamland.net/

Nov. 23, 2006

Hi, You probably recived heaps of mails about this, but I thought I'd send it just in case. The Western Australian State Government has voted to impement daylight savings on a trial basis for three years, starting on 3rd of December this year - Heaps of notice! "4. Trial period of daylight saving Despite the Standard Time Act 2005, from - (a) the hour of 2 a.m. on 3 December 2006 until the hour of 2 a.m. on 25 March 2007; and (b) the hour of 2 a.m. on 28 October 2007 until the hour of 2 a.m. on 30 March 2008; and (c) the hour of 2 a.m. on 26 October 2008 until the hour of 2 a.m. on 29 March 2009, summer time shall, throughout the State, be one hour in advance of standard time and shall be observed accordingly."

Just on the border of mass media: the December 2006 issue of Harper's includes the article "Clash of the Time Lords: Who will own the easure of our days?" by Michelle Stacey. The focus is the leap-second/leap-hour controversy; the Julian/Gregorian transition is covered in conjunction with this. Alas, there doesn't seem to be a Web version available. --ado

Time zone file on your FTP site
by Baig, Mirza [NCSUS] Nov. 17, 2006

Nov. 17, 2006

Hi: I have test tzdata2006m.tar.gz file on a Solaris 7 server (per SUN Microsystems recommendation). It seemed to have fixed the daylight saving time issue on Solaris 7 (since SUN does not officially support Solaris 7). But when the version of the tzdata file was posted (i.e. tzdata2006n.tar.gz), I tested that too, and it didn't fix the timezone issue. I was about to send this email, and realized that there is yet another version of tzdata file on your ftp site, i.e. tzdata2006o.tar.gz. Was the new version posted because someone has reported problem with tzdata2006n.tar.gz? Has the new data file been tested with Solaris 7? Thanks!

Western Australia planning for Daylight Saving Time starting 1 December 2006
by Eric Ulevik Nov. 7, 2006

Nov. 7, 2006

The state of Western Australia is planning to adopt daylight saving time on a trial basis till 31 March 2009. This has not yet been passed by parliament but is supported by both major parties. The initial period is 2am 1 December 2006 to 2am 25 March 2007. Subsequent periods are 2am on last Sunday in October till 2am on last Sunday in March. The Daylight Saving Bill 2006 can be found on http://www.parliament.wa.gov.au/. Unfortunately there is no fixed address. Source: http://www.thewest.com.au/default.aspx?MenuID=145&ContentID=10997

RE: Quetico (and other places in NW Ontario)

Chris, The map you sent of the Quetico park overview is more than sufficient for me to make a reasonable timezone. After all this is not rocket science, I'm intending to give an overview of the timezone for visual use, not for calculating if a specific latitude/longitude is inside the timezone or not. I'm using an ESRI shapefile map, you can check it out from downloading World Time Explorer beta version from http://www.worldtimeexplorer.com/wt20beta.zip and unzip and install it. I can give you a free full license if you want, so you can generate map colors for a specific date between 1850 and today. Otherwise the shareware version will give you 30 days of playing around, and the colors should correspond until 2007, except for a possible (undecided) change in West Australia of course! And PS, I presume you have (access to) a Windows PC, otherwise it will not be of much use! Linux die-hards, sorry! I was wondering if my border between Rainy_River (on GMT-6) area and the rest of Ontario (on GMT-5) is wrong, supposedly it should divide around 90° while in reality it divides around -89.34. This is from another map source where I copied this border from, but perhaps for timezone use I should move the border. It would be nice if you could plot the points from Quetico park (100 points would be fine, perhaps even too much). I don't know if you have a possibility to output to an ESRI shapefile. If not, a collection of the pure latitude/longitudes would be fine (decimal please, not radix 60). I will consider your comments about America/Winnipeg being one hour off each year, but it seems that even tz database is correct in this case? It looks like this: # From Paul Eggert (2006-04-10): # Shanks & Pottenger say Manitoba switched at 02:00 (not 02:00s) # starting 1966. Since 02:00s is clearly correct for 1967 on, assume # it was also 02:00s in 1966. ... Rule Winn 1963 only - Sep 22 2:00 0 S Rule Winn 1966 1986 - Apr lastSun 2:00s 1:00 D Rule Winn 1966 2005 - Oct lastSun 2:00s 0 S Rule Winn 1987 2005 - Apr Sun>=1 2:00s 1:00 D # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone America/Winnipeg -6:28:36 - LMT 1887 Jul 16 -6:00 Winn C%sT 2006 -6:00 Canada C%sT Since 2:00s standard time means 3:00 local time when leaving DST, we're OK? What would be the difference between the Kenora timezone and the others? Regards, - Jesper -----Original Message----- From: Chris Walton [mailto:Chris.Walton@telus.com] Sent: Domingo, 05 de Noviembre de 2006 1:24 To: jnorgard(a)prodigy.net.mx; tz(a)elsie.nci.nih.gov; Paul Eggert Subject: Quetico (and other places in NW Ontario) Jesper, It looks like the entire MNR site is down. It was working on Saturday morning (Toronto time). Hopefully it will come up soon! The maps on this site are actually scanned copies of paper maps; the idea being that you can view an image of the map before you fork out money for a paper copy. The resolution of the scanned images is terrible so the writing on the maps is virtually impossible to read. If you want a rough idea of the shape of the park have a peek at http://www.queticofoundation.org/maps/park_map.gif Let me know if you want me to generate a set of points or if you would prefer to do it yourself; I don't mind either way. I figure that the area could be roughly defined with about 100 points but to properly follow the park boundary would take around 2000 points. And now putting Quetico aside for a minute... you need to decide which zone to use for the "other" areas in Ontario west of 90°. According the TZ database, Fort Frances and Rainy River did not use daylight saving until 1974; this is why there is a dedicated zone called America/Rainy_River. So Rainy River and Fort Frances should use America/Rainy_River without question. Presumably the rest of the region west of 90° has used CST/CDT since WWII. According to the "zonetab" file, the region is supposed to use America/Winnipeg. America/Winnipeg results in incorrect times for one hour each year from 1966 through to 2005. This is because Manitoba "used" to change the clocks at 3:00a.m. every fall. The practice stopped this year. Ontario has always changed the clocks 2:00a.m. America/Rainy_River gives correct times for the entire region from 1974 onwards. Personally I think that America/Rainy_River is the better choice for the entire region because it provides correct rules for the last 32 years. Technically there should be another zone called America/Kenora but I doubt anybody wants to bother creating it. If it were up to me I would merge zones that have been the same for at least 25 years and create entries in the "backward" file for compatibility; but I know this would be against the official rules! -chris

RE: Quetico
by Jesper Norgaard Welen Nov. 5, 2006

Nov. 5, 2006

Chris, Unfortunately I'm getting this error when trying to access the Ontario Ministry of Natural Resources: http://themnrstore.mnr.gov.on.ca Microsoft OLE DB Provider for SQL Server error '80004005' [DBMSSOCN]General network error. Check your network documentation. //global.asa, line 181 I'm creating a world map, which doesn't have a huge accuracy, however, it is zoomable, so the simpler the jagged borders I make the more a curve in a (timezone or country) border looks wrong. There are no splines or other sophisticated map boundaries (fractals!?). I will be plotting the Quetico map with the least accurate technology, with a mouse click on each point in the boundary :-( That said, I would like to get as much accuracy as I can get, although it is also an issue not to have too many points for a boundary, because the size of the map data will blow up disproportionately. Many of the country borders I got from a pre-made map, and this map has more accuracy in some areas and less in others. I tend to want more accuracy with small islands or timezones, while less on bigger outlines, like Quebec or Ontario. I *do* understand that this practice is in contradiction with the current legislation, but then I want to document current practice when it has a tendency to be official, for instance official park personnel would use GMT-5 everywhere in the park when reporting something on the ground inside the park area, while park visitants might have a different time, as they please.

It has a perimeter that is roughly 300km long; it has a few straight sections but much of it follows lakes and rivers. Here is a sample map; this is part of the perimeter that is made of nice straight lines: http://themnrstore.mnr.gov.on.ca/english/map.asp?tid=0&zoom=5&map=2015650053 500&DisplayImage=True Here is another sample map; (look for the black dashed line where it follows the shore of Three Mile Lake and Quetico River... the line is not straight!): http://themnrstore.mnr.gov.on.ca/english/map.asp?tid=0&zoom=5&map=2015550053 600&DisplayImage=True Here is another sample map showing part of the perimeter that follows the Ontario/Minnesota (Canada/US) border: http://themnrstore.mnr.gov.on.ca/english/map.asp?tid=0&zoom=5&map=2015580053 400&DisplayImage=True If you are going to try and define time zone boundaries, the jagged international border needs to be dealt with regardless of whether you place Quetico in America/Atikokan or America/Rainy_River. The same border is part of the northern perimeter of America/Chicago. Obviously this is not the only part of the world where boundaries don't follow straight lines. How do you usually handle jagged borders? Do you approximate with a lot of single points or do you approximate with a series of mathematical splines? How much accuracy are you looking for? The scale of the map that is used to get the data makes a huge difference! Before we take this further... Here is a summary of time practices for Atikokan & Quetico... Nothing new but please read. I just want to make sure we are all on the same page. The Township of Atikokan and Quetico Provincial Park both lie west of 90° longitude. Based on Ontario Legislation, the time observed in this region should be CST/CDT (UTC-6 in winter and UTC-5 in summer). The local mining companies don't like the clocks moving forwards and backwards and pressured the Township of Atikokan to remain on UTC-5 year round. The tradition probably goes back to the end of World War II. The Township has never had any by-law or formal documentation in place to cover the practice. If there was such a by-law it would automatically be invalidated by the Ontario Time Act. Quetico Provincial Park is a relatively large wilderness park that is situated very close to Atikokan (the southeast corner of Atikokan township is actually located in the park). Total land area of the park is 4758 square km. For comparison, the park is just a little smaller than the province of Prince Edward Island. For people that like US comparisons, it is bigger than Rhode Island but smaller than Delaware. There are no roads in the park other than those at the main campground. The primary means of travel in the park (in summer months) is the canoe. The head office of Quetico Provincial Park is in the Township of Atikokan. The park staff (Ontario Ministry of Resources employees) use "Atikokan time" for official business year round. (I got confirmation of this back in July from the park superintendent.) Campers, canoeists, skiers, hikers, and those who prefer snow shoes can set their watches as they please without being shot (because we don't use guns in Canada). In the summer months a.k.a. the tourist season, America/Atikokan, America/Rainy_River, America/Winnipeg, and America/Chicago are on UTC-5 so most visitors to Quetico park would never know there is anything special about "Atikokan time". The hour difference between America/Atikokan and the other time zone regions only shows up in the winter when the tourists have gone home and there are presumably very few people using the park. The bottom line is that we are dealing with an area where visitors will use what ever time they please but any local record keeping will be done with UTC-5. For the purposes of defining time zone boundaries on paper (or computer), I am not claiming that Quetico "must" be placed in the America/Atikokan time zone... but I will try and support anybody that decides to do so. -chris

RE: Nipigon and Atikokan

Thanks, Chris >Nipigon Township: >Northern boundary: 49 degrees 02 minutes 20 seconds N >Eastern boundary: 88 degrees 14 minutes 0 seconds W >Southern boundary: 48 degrees 58 minutes 20 seconds N <--updated >Western boundary: 88 degrees 26 minutes 0 seconds W Thanks for the updated coordinates. I think I will include Quetico Provinicial Park in my Atikokan timezone. Do you happen to have the coordinates? I tried with the links you sent, but the PDF files load very slowly, and I don't see the coordinates clearly. >If you are making a time zone map you have to decide whether to lump Quetico >Provincial Park in with Atikokan. Quetico is a large wilderness park. At 4758 >square kilometres it is more than ten times the size of Atikokan itself.

If I understand the new legislation, >the time zone boundary will no longer follow the 63rd meridian starting next year. >See my notes in: http://www3.sympatico.ca/c.walton/canada_dst.html I'm not quite sure what are the changes from previous *actual* time keeping in the regions and the new laws to be applied Jan 1, 2007. As far as I can see the laws are merely confirming the practice that was already used. One exception could be the Anticosti Island, where this is cut on 2 by the map on http://time5.nrc.ca/webclock_e.shtml while it seems that the permanent inhabitants, mostly situated on the west side of the island, always has used EST/EDT on the whole island, thus making the previous link wrong about the eastern part of the island. But as I understand it, the new law is now reflecting the current practice even in this case. Regards, - Jesper
