Dear list, First of all, I would like to apologize for the confusion I might have caused with my previous emails. The corrections for the brazilian rules and zones I sent where already included in tzdata. I hope this haven't created any problems. Now I send another set of corrections for the brazilian tz data. I have just finished a full review of its rules and zoneinfo from the decrees list at the Brazilian National Observatory (main source of time info in Brazil, the same source already used by previous authors) with the following problems identified and corrected: 1. The effects of decrees 52700 (1963-10-18) and 53071 (1963-12-03) weren't correctly represented by the data as what they really have done was to make a set of states start DST at 1963-10-23 00:00 and the rest of the country to start DST at 1963-12-09 00:00. Fix: change the rule and all affected zones (almost all of them). Also had to create a new Brasilia zone to acomodate the diferences between Sao_Paulo zone and Goias (GO), Distrito Federal (DF), Parana (PR), Santa Catarina (SC), Rio Grande do Sul (RS). 2. The starting time of DST for 1966 was wrong as the 57843 decree stablishes that DST shall begin at 1966-03-01 01:00 and on 1st of March 00:00 from 1967 and on. Fix: new rule for DST start at 1966. 3. Decree 1252 (1994-09-22) defines that the previous states minus AM _AND_ MT states would have DST during 1994/1995 summer. The author of the previous comment probably relied on the Brazilian National Observatory resume of the decree - which is wrong - and not on the actual decree itself (also available at the Brazilian National Observatory site). Fix: America/Cuiaba zone fix. 4. Fernando de Noronha island had wrong timezone info as it should include all DSTs for the Pernambuco state after 1988 as Fernando de Noronha island became part of the Pernambuco state after the brazilian contitution of 1988. If someone has any doubt about it, please check decree 96676 (pre 1988) which clearly includes Pernambuco state, Fernando de Noronha and Atlantic islands. Compare with decree 98077 (pos 1988) which clearly includes Pernambuco state and Atlantic islands (doesn't mention Fernando de Noronha because it already mentioned Pernambuco). Fix: Include all DSTs for Pernambuco after 1988 and create new zone Atol_das_Rocas for the atlantic islands. Maybe this new zone should be called Brazilian_Atlantic_Islands? Too long? 5. America/Sao_Paulo zone had a DST during the whole 1964. I can't see where it came from. There is no decree mentioning it. Fix: Remove it spurious zone info. The patch I am including here is based on the data available at ftp://elsie.nci.nih.gov/pub/ dated 10/06/2003 01:41:00 PM. If someone has any comments on these changes, please send a copy to my personal email as I not sure if I am already subscribed to this list.

Time in Jersey
by Joseph S. Myers Nov. 3, 2003

Nov. 3, 2003

A while back, Geraint Jennings <http://www.societe-jersiaise.org/geraint/jerriais> sent me some additional information about time in Jersey, with a reference to www.jerseylegalinfo.je for laws including the 1898 law adopting GMT. I've now got round to updating my site <http://www.srcf.ucam.org/~jsm28/british-time/> accordingly. He also sent the following newspaper article he wrote about the adoption of GMT in Jersey (published at the end of October so I can now send it to this list). As I doubt many people on this list read J�rriais at all, I'm only including the English translation, "intended as a crib to enable English-speakers to read the original so it's a bit clunky and literal". ====================================================================== Jersey Time Do you like the change of time? Putting back the clocks in Autumn, we're used to that at least, but in 1862 there there were lots of townsfolk who were very angry with the putting forward of the time. The thing is, in the month of May 1862 it was decided to put the new clock in the steeple of the Parish Church of St. Helier on Greenwich time, instead of Jersey time, seeing as the captains of the steamships which travelled according to the timetables of English companies had asked for that arrangement. But that's what didn't please Jersey pilots and seamen. The fourth of June therefore, a hundred and sixteen Principals of the Parish called a Parish Assembly so as to put back the clock to Jersey time - why do such nonsense to please the English? And what's more, an election for Churchwarden had been annulled because the nominations had been posted in the official notice box at three minutes past eleven - by the Church clock - but at five to eleven by Jersey time. The nominations should have been placed in the box after eleven o'clock - but the question was: which eleven o'clock? The Assembly decided that one must ignore foreign time, and on the fifth of June therefore the clock began to show Jersey time. It wasn't until 1898 that the States passed a law to adopt Greenwich mean time in Jersey, which became the official time at around 4pm on the 11th June. What do you think? Would you like to go back to Jersey time, with a difference of eight minutes and twenty-seven seconds with the UK? Alas, it's no longer our Parishes which are in charge of the time!

Peru DST
