[somehow OT] "undoing" manual tzdata compilation on a Mac
by Mariano Absatz - El Baby April 2, 2010

April 2, 2010

Hi, I know Argentina has a long history of doing last minute changes about our timezones including inter-provincial anarchy. However, tzdata is easy enough to quickly adapt to this changes, and if you're somehow savvy, it is quite easy to fix things on your own. Last October, Argentina decided not to apply DST this (Southern) summer on the last minute and this was reflexed on tzdata2009p published on October 26th. Since Apple didn't immediately made this changes, knowing that OS X is actually running on top of some kind of BSD and actually finding zic and /usr/share/zoneinfo in it, I volunteered "fixing" a friend's macbook pro. I simply compiled the southamerica file from tzdata2009p and that was it... right? wrong! This actually made the mac go somehow crazy since it also uses some ICU files which I don't know how to handle. My friend ended up using Chile's time during the summer and Uruguay's time after Uruguay's DST period ended. Since a week ago the non-existent DST for Argentina would have ended, I told him to try again Argentina's time but it keeps being inconsistent. Another mac he has at home has now the correct time. Does anyone know how to restore the original OS X tzdata files without reinstalling the OS? I know nothing about its packaging system... Mac users seem to rely on "Apple update" service but I probably f##k'd it up when I overwrote some files under /usr/share/zoneinfo. Any help (or links to better places) will be greatly appreciated. -- Mariano Absatz - "El Baby" baby(a)baby.com.ar www.clueless.com.ar -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- I haven't lost my mind, I have it backed up on tape somewhere. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- * TagZilla 0.066 * http://tagzilla.mozdev.org

How can I reduce size of zoneinfo compiled binary files?
by Dominique Pellé March 31, 2010

March 31, 2010

Hi I'd like to compile the zoneinfo files for an embedded system where I'd like to strip as much information as possible. I see that all the zoneinfo binary files take 6.1Mb: $ du -s -h /usr/share/zoneinfo/ 6,1M /usr/share/zoneinfo/ If I run the zic compiler, it produces the following file sizes for example for Europe/Paris, Europe/Amsterdam, Europe/Berlin: $ mkdir -p test $ zic -d test europe $ ls -l test/Europe/{Paris,Amsterdam,Berlin} -rw-r--r-- 1 pel pel 2917 2010-03-31 22:09 test/Europe/Amsterdam -rw-r--r-- 1 pel pel 2309 2010-03-31 22:09 test/Europe/Berlin -rw-r--r-- 1 pel pel 2945 2010-03-31 22:09 test/Europe/Paris Since I don't care about time zone rules in the past for my embedded application, I'd like to compile only the rules starting at year >= 2010 for example (in other words, I'd like to ignore all historical rules older than < 2010). I would then expect output binary files to become not only smaller, but also many of them should also identical since most countries in Europe follow the same rules nowadays (Europe/Amsterdam, Europe/Berlin and Europe/Paris in my above example should become identical). So I should then be able to create links to most of them. However, I don't see any command line option in the 'zic' compiler to let me compile rules from >= 2010 only, or am I missing something? I suppose that I could edit the input ASCII file 'europe', 'asia' (etc) to remove rules in the past, but it seems error prone (especially since input text files can be updated regularly). Is there a simpler solution? Thanks -- Dominique

There was a photo # and a sketch map showing some of the sightlines involved. One paragraph # of the text said: # # `An old stone obelisk marking a forgotten terrestrial meridian stands # beside the river at Kew. In the 18th century, before time and longitude # was standardised by the Royal Observatory in Greenwich, scholars observed # this stone and the movement of stars from Kew Observatory nearby. They # made their calculations and set the time for the Horse Guards and Parliament, # but now the stone is obscured by scrubwood and can only be seen by walking # along the towpath within a few yards of it.' # # I have a one inch to one mile map of London and my estimate of the stone's # position is 51 deg. 28' 30" N, 0 deg. 18' 45" W. The longitude should # be within about +-2". The Ordnance Survey grid reference is TQ172761. # # [This yields GMTOFF = -0:01:15 for London LMT in the 18th century.] # From Paul Eggert (1993-11-18): # # Howse writes that Britain was the first country to use standard time. # The railways cared most about the inconsistencies of local mean time, # and it was they who forced a uniform time on the country. # The original idea was credited to Dr. William Hyde Wollaston (1766-1828) # and was popularized by Abraham Follett Osler (1808-1903). # The first railway to adopt London time was the Great Western Railway # in November 1840; other railways followed suit, and by 1847 most # (though not all) railways used London time. On 1847-09-22 the # Railway Clearing House, an industry standards body, recommended that GMT be # adopted at all stations as soon as the General Post Office permitted it. # The transition occurred on 12-01 for the L&NW, the Caledonian, # and presumably other railways; the January 1848 Bradshaw's lists many # railways as using GMT. By 1855 the vast majority of public # clocks in Britain were set to GMT (though some, like the great clock # on Tom Tower at Christ Church, Oxford, were fitted with two minute hands, # one for local time and one for GMT). The last major holdout was the legal # system, which stubbornly stuck to local time for many years, leading # to oddities like polls opening at 08:13 and closing at 16:13. # The legal system finally switched to GMT when the Statutes (Definition # of Time) Act took effect; it received the Royal Assent on 1880-08-02. # # In the tables below, we condense this complicated story into a single # transition date for London, namely 1847-12-01. We don't know as much # about Dublin, so we use 1880-08-02, the legal transition time. # From Paul Eggert (2003-09-27): # Summer Time was first seriously proposed by William Willett (1857-1915), # a London builder and member of the Royal Astronomical Society # who circulated a pamphlet ``The Waste of Daylight'' (1907) # that proposed advancing clocks 20 minutes on each of four Sundays in April, # and retarding them by the same amount on four Sundays in September. # A bill was drafted in 1909 and introduced in Parliament several times, # but it met with ridicule and opposition, especially from farming interests. # Later editions of the pamphlet proposed one-hour summer time, and # it was eventually adopted as a wartime measure in 1916. # See: Summer Time Arrives Early, The Times (2000-05-18). # A monument to Willett was unveiled on 1927-05-21, in an open space in # a 45-acre wood near Chislehurst, Kent that was purchased by popular # subscription and open to the public. On the south face of the monolith, # designed by G. W. Miller, is the the William Willett Memorial Sundial, # which is permanently set to Summer Time. # From Winston Churchill (1934-04-28): # It is one of the paradoxes of history that we should owe the boon of # summer time, which gives every year to the people of this country # between 160 and 170 hours more daylight leisure, to a war which # plunged Europe into darkness for four years, and shook the # foundations of civilization throughout the world. # -- <a href="http://www.winstonchurchill.org/fh114willett.htm"> # "A Silent Toast to William Willett", Pictorial Weekly # </a> # From Paul Eggert (1996-09-03): # The OED Supplement says that the English originally said ``Daylight Saving'' # when they were debating the adoption of DST in 1908; but by 1916 this # term appears only in quotes taken from DST's opponents, whereas the # proponents (who eventually won the argument) are quoted as using ``Summer''. # From Arthur David Olson (1989-01-19): # # A source at the British Information Office in New York avers that it's # known as "British" Summer Time in all parts of the United Kingdom. # Date: 4 Jan 89 08:57:25 GMT (Wed) # From: Jonathan Leffler # [British Summer Time] is fixed annually by Act of Parliament. # If you can predict what Parliament will do, you should be in # politics making a fortune, not computing. # From Chris Carrier (1996-06-14): # I remember reading in various wartime issues of the London Times the # acronym BDST for British Double Summer Time. Look for the published # time of sunrise and sunset in The Times, when BDST was in effect, and # if you find a zone reference it will say, "All times B.D.S.T." # From Joseph S. Myers (1999-09-02): # ... some military cables (WO 219/4100 - this is a copy from the # main SHAEF archives held in the US National Archives, SHAEF/5252/8/516) # agree that the usage is BDST (this appears in a message dated 17 Feb 1945). # From Joseph S. Myers (2000-10-03): # On 18th April 1941, Sir Stephen Tallents of the BBC wrote to Sir # Alexander Maxwell of the Home Office asking whether there was any # official designation; the reply of the 21st was that there wasn't # but he couldn't think of anything better than the "Double British # Summer Time" that the BBC had been using informally. # http://student.cusu.cam.ac.uk/~jsm28/british-time/bbc-19410418.png # http://student.cusu.cam.ac.uk/~jsm28/british-time/ho-19410421.png # From Sir Alexander Maxwell in the above-mentioned letter (1941-04-21): # [N]o official designation has as far as I know been adopted for the time # which is to be introduced in May.... # I cannot think of anything better than "Double British Summer Time" # which could not be said to run counter to any official description. # From Paul Eggert (2000-10-02): # Howse writes (p 157) `DBST' too, but `BDST' seems to have been common # and follows the more usual convention of putting the location name first, # so we use `BDST'. # Peter Ilieve (1998-04-19) described at length # the history of summer time legislation in the United Kingdom. # Since 1998 Joseph S. Myers has been updating # and extending this list, which can be found in # <a href="http://student.cusu.cam.ac.uk/~jsm28/british-time/"> # History of legal time in Britain # </a> # From Joseph S. Myers (1998-01-06): # # The legal time in the UK outside of summer time is definitely GMT, not UTC; # see Lord Tanlaw's speech # <a href="http://www.parliament.the-stationery-office.co.uk/pa/ld199697/ldhansrd/pdvn…"> # (Lords Hansard 11 June 1997 columns 964 to 976) # </a>. # From Paul Eggert (2006-03-22): # # For lack of other data, follow Shanks & Pottenger for Eire in 1940-1948. # # Given Ilieve and Myers's data, the following claims by Shanks & Pottenger # are incorrect: # * Wales did not switch from GMT to daylight saving time until # 1921 Apr 3, when they began to conform with the rest of Great Britain. # Actually, Wales was identical after 1880. # * Eire had two transitions on 1916 Oct 1. # It actually just had one transition. # * Northern Ireland used single daylight saving time throughout WW II. # Actually, it conformed to Britain. # * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18. # Actually, that date saw the usual switch to summer time. # Standard time was not changed until 1968-10-27 (the clocks didn't change). # # Here is another incorrect claim by Shanks & Pottenger: # * Jersey, Guernsey, and the Isle of Man did not switch from GMT # to daylight saving time until 1921 Apr 3, when they began to # conform with Great Britain. # S.R.&O. 1916, No. 382 and HO 45/10811/312364 (quoted above) say otherwise. # # The following claim by Shanks & Pottenger is possible though doubtful; # we'll ignore it for now. # * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00. # # # Whitman says Dublin Mean Time was -0:25:21, which is more precise than # Shanks & Pottenger. # Perhaps this was Dunsink Observatory Time, as Dunsink Observatory # (8 km NW of Dublin's center) seemingly was to Dublin as Greenwich was # to London.

"old style" # might be a reference to the Julian calendar as opposed to Gregorian, or it # might mean something else (???). # # From Paul Eggert (2006-03-22): # The Iceland Almanak, Shanks & Pottenger, and Whitman disagree on many points. # We go with the Almanak, except for one claim from Shanks & Pottenger, namely # that Reykavik was 21W57 from 1837 to 1908, local mean time before that. # # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Iceland 1917 1918 - Feb 19 23:00 1:00 S Rule Iceland 1917 only - Oct 21 1:00 0 - Rule Iceland 1918 only - Nov 16 1:00 0 - Rule Iceland 1939 only - Apr 29 23:00 1:00 S Rule Iceland 1939 only - Nov 29 2:00 0 - Rule Iceland 1940 only - Feb 25 2:00 1:00 S Rule Iceland 1940 only - Nov 3 2:00 0 - Rule Iceland 1941 only - Mar 2 1:00s 1:00 S Rule Iceland 1941 only - Nov 2 1:00s 0 - Rule Iceland 1942 only - Mar 8 1:00s 1:00 S Rule Iceland 1942 only - Oct 25 1:00s 0 - # 1943-1946 - first Sunday in March until first Sunday in winter Rule Iceland 1943 1946 - Mar Sun>=1 1:00s 1:00 S Rule Iceland 1943 1948 - Oct Sun>=22 1:00s 0 - # 1947-1967 - first Sunday in April until first Sunday in winter Rule Iceland 1947 1967 - Apr Sun>=1 1:00s 1:00 S # 1949 Oct transition delayed by 1 week Rule Iceland 1949 only - Oct 30 1:00s 0 - Rule Iceland 1950 1966 - Oct Sun>=22 1:00s 0 - Rule Iceland 1967 only - Oct 29 1:00s 0 - # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Atlantic/Reykjavik -1:27:24 - LMT 1837 -1:27:48 - RMT 1908 # Reykjavik Mean Time? -1:00 Iceland IS%sT 1968 Apr 7 1:00s 0:00 - GMT # Italy # # From Paul Eggert (2001-03-06): # Sicily and Sardinia each had their own time zones from 1866 to 1893, # called Palermo Time (+00:53:28) and Cagliari Time (+00:36:32). # During World War II, German-controlled Italy used German time. # But these events all occurred before the 1970 cutoff, # so record only the time in Rome. # # From Paul Eggert (2006-03-22): # For Italian DST we have three sources: Shanks & Pottenger, Whitman, and # F.

Svalbard was declared # as a part of Norway by law of 1925-07-17 no 11, section 4 and Jan # Mayen by law of 1930-02-27 no 2, section 2. (From # http://www.lovdata.no/all/nl-19250717-011.html and # http://www.lovdata.no/all/nl-19300227-002.html) The law/regulation # for normal/standard time in Norway is from 1894-06-29 no 1 (came # into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a # part of this law since 1925/1930. (From # http://www.lovdata.no/all/nl-18940629-001.html ) I have not been # able to find if Jan Mayen used a different time zone (e.g. -0100) # before 1930. Jan Mayen has only been "inhabitated" since 1921 by # Norwegian meteorologists and maybe used the same time as Norway ever # since 1921. Svalbard (Arctic/Longyearbyen) has been inhabited since # before 1895, and therefore probably changed the local time somewhere # between 1895 and 1925 (inclusive). # From Paul Eggert (2001-05-01): # # Actually, Jan Mayen was never occupied by Germany during World War II, # so it must have diverged from Oslo time during the war, as Oslo was # keeping Berlin time. # # <http://home.no.net/janmayen/history.htm> says that the meteorologists # burned down their station in 1940 and left the island, but returned in # 1941 with a small Norwegian garrison and continued operations despite # frequent air ttacks from Germans. In 1943 the Americans established a # radiolocating station on the island, called "Atlantic City". Possibly # the UTC offset changed during the war, but I think it unlikely that # Jan Mayen used German daylight-saving rules. # # Svalbard is more complicated, as it was raided in August 1941 by an # Allied party that evacuated the civilian population to England (says # <http://www.bartleby.com/65/sv/Svalbard.html>). The Svalbard FAQ # <http://www.svalbard.com/SvalbardFAQ.html> says that the Germans were # expelled on 1942-05-14. However, small parties of Germans did return, # and according to Wilhelm Dege's book "War North of 80" (1954) # <http://www.ucalgary.ca/UofC/departments/UP/1-55238/1-55238-110-2.html> # the German armed forces at the Svalbard weather station code-named # Haudegen did not surrender to the Allies until September 1945. # # All these events predate our cutoff date of 1970.

Samara and Izhevsk in Russia will move to Moscow Time Zone on March 28, 2010
by Alexander Krivenyshev March 22, 2010

March 22, 2010

According to the Russian media, Prime Minister of Russia V. Putin signed a Resolution of the Government "ON THE APPLICATION IN THE TERRITORY OF THE UDMURT REPUBLIC SECOND TIME ZONE" 2 Russian regions (MSK +1, GMT+4): Samara region, capital Samara Udmurt Republic (Udmurtia), capital Izhevsk will move to Moscow Time Zone (MSK, GMT+3) on March 28, 2010. (in Russian) http://www.infox.ru/authority/state/2010/03/20/Rossiya_lishilas_odn.phtml Prime Minister of Russia V. Putin signed a Resolution of the Government "ON THE APPLICATION IN THE TERRITORY OF THE UDMURT REPUBLIC SECOND TIME ZONE" Draft Resolution of the Government could be found on The Ministry of Industry and Trade of the Russian Federation http://www.minprom.gov.ru/docs/ce/38 (in Russian) or http://www.worldtimezone.com/dst_news/dst_news_russia13.html As reference, both 2 regions (Udmurt Republic and Samara) are the only regions left in MSK +1 (GMT+4) Time Zone of Russia (blue color our Russian time zones map on) http://www.worldtimezone.com/time-russia24.php This is probably one of the transitional stage in the reshaping of Time Zones in Russia. As in the future, some regions from current time zone (MSK +2, GMT+5)- Perm, Kurgan, Chelyabinsk, Ekaterinburg (Yekaterinburg) probably will move to "empty" Russian time zone (MSK +1, GMT+4) Alexander Krivenyshev, http://www.worldtimezone.com

by Olson, Arthur David (NIH/NCI) [E] March 22, 2010

March 22, 2010

The files... ftp://elsie.nci.nih.gov/pub/tzcode2010f.tar.gz ...and... ftp://elsie.nci.nih.gov/pub/tzdata2010f.tar.gz ...are now available; these reflect the changes circulated last week on the time zone mailing list. For those seeking to avoid version thrash, I'm guessing that tzdata2010g will appear next week; the proposed changes (based on reports from Alexander Krivenyshev) should appear in two days. --ado
