UK timezones
by pla＠sktb.demon.co.uk Jan. 20, 1999

Jan. 20, 1999

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

changes for Nicaragua and Fiji
by Steffen Thorsen Dec. 29, 1998

Dec. 29, 1998

Dear Sirs, Nicaragua seems to be back at -6:00 but I have not been able to find when they changed from -5:00, so I have not included any patch for this change. (I got this information from a citizen in Managua. I've also tried telnet ibw.com.ni 13 which is located there, and it shows -6:00 to UTC) It seems like Fiji has started using DST now, but they provide information only for the change this year. I have tried to make a diff for australasia and had to make a new rule for "Fiji" because of the DST. Patch for Fiji is included at the end. Leo Brandewie <lbrand(a)earthlink.net> got this information from the Fiji Government: Forwarded: Here's what I got back from the Fijian Government. Note that it fails to provide general rules, and due to a nasty coincidence we cannot infer them without risk. Since Nov. 1 and Feb 28 are both Sundays, we can assume but not prove that it starts on the first Sun. in Nov. and ends on the last Sun. in Feb. Hope this helps, Leo [ Part 2: "Included Message" ] Date: Tue, 29 Dec 1998 14:20:20 +0000 From: Fiji Government <info(a)fiji.gov.fj> To: Leo Brandewie <lbrand(a)earthlink.net> Subject: Re: Daylight Savings Leo Below is a Government press release on the 5th of October on Daylight Savings. "The Minister for Labour and Industrial Relations, Mr Vincent Lobendahn declared Daylight Saving to commence on November 1st, 1998. This means that at 2am on Sunday 1 November, clocks will be put forward to 3am and at 3am on Sunday 28 February 1999, clocks will be put back to 2am. The concept of daylight saving means that extra daylight will be available at the end of each day during the daylight saving period. The advantages of of daylight saving include: more time for sport, family recreation, gardening and other outdoor activities, savings in respect of electricity, reduction in nightime road accidents, increase in economic activity, with longer daylight hours for productive work activities, benefits to tourism by making best use of available daylight. According to a spokesman from the Ministry of Labour and Industrial Relations, Sunday morning has been chosen to ensure the least disruption to work activities as only shift workers employed at that time will be affected. The spokesman said the people will have to put their clocks forward by one hour before they go to bed on Saturday 31 October, which will ensure their time is correct when they wake up on Sunday morning. The same will apply on Saturday, 27 February next year, except that people will need to put their clocks back by one hour before they go to bed. However, shift workers employed at the time that clocks are officially changed will be affected. This means that a shift worker working an eight hour night shift starting at 10pm on Saturday 31 October and finishing at 6am on Sunday, 1 November 1998 will start and finish at those times but will work only seven hours due to the change in time. However, the person will still be entitled to eight hours pay. And a person who works the same shift from 10pm on Saturday 27 February until 6am on Sunday 28 February 1999 will work nine hours due to the change in time. The person must be paid for the extra hour and if the contract of service provides for overtime to be paid after eight hours, he or she would be entitled to the overtime rate of pay for the ninth hour of work." -END- diff -u australasia.old australasia --- australasia.old Thu Sep 24 16:46:09 1998 +++ australasia Tue Dec 29 11:31:06 1998 @@ -197,9 +197,15 @@ Zone Indian/Cocos 6:30 - CCT # Cocos Islands Time # Fiji + +# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S +Rule Fiji 1998 only - Nov 1 2:00 1:00 - +Rule Fiji 1999 only - Feb 28 3:00 0:00 - + # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Pacific/Fiji 11:53:40 - LMT 1915 Oct 26 # Suva - 12:00 - FJT # Fiji Time + 12:00 - FJT 1998 Nov 1 + 12:00 Fiji FJT # Fiji Time # French Polynesia # Zone NAME GMTOFF RULES FORMAT [UNTIL]
