Can someone please tell me whether Argentina did, or did not, discontinue observing a fixed, year-round time this year (a time that many would consider "daylight-saving" time), which would have put its clocks back an hour sometime recently (the first change in a decade)? Its powers-that-be seem to have changed their minds several times, but the last I heard, they'd "recinded" the proposal to "introduce daylight-saving time" (quotes only from memory and therefore questionable), which I took to mean they'd decided against re-introducing a non-daylight-saving period, because they seemed to have decided in favour of the status quo, Didn't I read somewhere that someone claimed that the proposed change would actually cause an increase in power consumption, rather than a decrease? This would have to be a classic case of multiple negations combined with mind-boggling ambiguity and perhaps translation difficulties. --Alex _______________ Alex LIVINGSTON IT, Australian Graduate School of Management (AGSM), UNSW SYDNEY NSW 2052 Fax: +61 2 9931-9349 / Phone: +61 2 9931-9264 / Time: UTC + 10 or 11 h.

Yes. My understanding is that the Argentina has not adjusted its wall clocks since 1993, and does not currently plan to adjust them in the future. However, Argentina did observe DST last summer because it subtracted an hour from the standard-time offset during the period that it was observing DST. That is, ARST was 3 hours behind UTC in 1999/2000, even though it was 2 hours behind UTC in 1992/1993. The transitions starting with 1992/1993 are as follows: Sun Oct 18 02:59:59 1992 UTC = Sat Oct 17 23:59:59 1992 ART isdst=0 Sun Oct 18 03:00:00 1992 UTC = Sun Oct 18 01:00:00 1992 ARST isdst=1 Sun Mar 7 01:59:59 1993 UTC = Sat Mar 6 23:59:59 1993 ARST isdst=1 Sun Mar 7 02:00:00 1993 UTC = Sat Mar 6 23:00:00 1993 ART isdst=0 Sun Oct 3 02:59:59 1999 UTC = Sat Oct 2 23:59:59 1999 ART isdst=0 Sun Oct 3 03:00:00 1999 UTC = Sun Oct 3 00:00:00 1999 ARST isdst=1 Fri Mar 3 02:59:59 2000 UTC = Thu Mar 2 23:59:59 2000 ARST isdst=1 Fri Mar 3 03:00:00 2000 UTC = Fri Mar 3 00:00:00 2000 ART isdst=0 This understanding is reflected in my latest proposed patch to tzcode. If it's incorrect, please let me know, ideally by citing authoritative sources.
