US vs. European Date Notation
by Markus Kuhn June 8, 1999

June 8, 1999

May be someone on this list has some insight about this topic: A journalist of the Wall Street Journal has contacted me as part of his research for a feature article about date notations. He noted that more and more Americans now start to use the European day, month, year notation instead of the traditional month, day, year, and he now realizes that thanks to ISO 8601 all this is moving into the wrong direction anyway. He would be very interested into any pointers of the history of these three date notations, and actually I am quite interested as well. Why do Americans write dates as "December 31, 1999" while Europeans write "31 December 1999", etc.? Why are in East Asia Bigendian dates more common? Markus -- Markus G.

How widespread is this time-conversion bug?
by D. J. Bernstein Feb. 6, 1999

Feb. 6, 1999

Dennis Ritchie reported on comp.lang.c.moderated that Plan 9's gmtime() didn't believe that 2000 was a leap year. The problem is that it was working with tm_year instead of tm_year + 1900. Peter Seebach reported that BSD/OS had the same problem. I wonder when these bugs were added. The tz code looks fine. I thought BSD/OS was using tz; did they switch to another library? ---Dan

standard time in Japanese antarctic stations
by Hideyuki Suzuki Feb. 6, 1999

Feb. 6, 1999

I'd like the following information about Japanese antarctic stations to be written in tzdata. Japan has two year-round bases: Syowa and Dome Fuji. (http://www.delm.tas.gov.au/comnap/members.html#Japan) In all Japanese stations, +0300 is used as the standard time. (http://www.crl.go.jp/uk/uk201/basyo.htm (Japanese) and information from KAMO Hiroyasu <wd(a)ics.nara-wu.ac.jp>) Syowa station, which is the first antarctic station of Japan, was established on 1957-01-29. Since Syowa station is still the main station of Japan, it's appropriate for the principal location. The location of these stations are: Showa: -690022+0393524 Dome Fuji: -771901+0394212 (http://www.nipr.ac.jp/english/jare.html, http://www.nipr.ac.jp/jp/station/station.html (Japanese)) I noticed that the URL http://earth.agu.org/amen/nations.html at the beginning of the file antarctica does not exist. There is the corresponding page at COMNAP: http://www.delm.tas.gov.au/comnap/station.html -- hideyuki

-----Original Message----- From: pla(a)sktb.demon.co.uk [SMTP:pla@sktb.demon.co.uk] Sent: Wednesday, January 20, 1999 1:42 PM To: tz(a)elsie.nci.nih.gov Subject: UK timezones Since May 1994, one small part of mainland Britain has been running on a different timezone from the rest of the UK. The exception is Cheriton Terminal, the rail terminal at the UK end of the Channel Tunnel (run by the Eurotunnel Concession) at Cheriton, Folkestone, Kent. Cheriton Terminal runs on Concession Time (abbreviation CT) in winter and Concession Time (abbreviation CT) in summer. You might think the names and abbreviations are confusing and stupid, I couldn't possibly comment. CT is formally defined to be equivalent to French Civil Time. So at present, given the way the EU timezone rules operate and the fact that the French have not yet persuaded the EU to let them abandon daylight savings time, CT is one hour ahead of GMT in winter and one hour ahead of BST in summer. This information came via Clive Feather of Demon Internet who puzzled many Demon Internet users by asking which part of the UK was in a different timezone. It goes without saying that Clive is a rail enthusiast... --Paul
