In reviewing those changes I noticed one howler: they didn't update America/Eirunepe, which also moved from ACT (UTC-5) to AMT (UTC-4) on June 24. Here's a proposed patch that integrates this change, plus some other, less-important changes, some of which I have been saving up for quite some time. Sorry about the delay. By the way, I had trouble with the patch that removed the accent, due to mail-encoding issues (is it UTF-8 or Latin-1? it matters). Possibly you'll have the same problem with my patch enclosed below, too. Given this problem with emailed patches, I'd prefer to avoid non-ASCII characters even in the comments, for a while longer anyway. To try to be a bit safer I'll also attach the proposed patch as a binary file. The enclosed patch is relative to tzdata2008c, and contains the following changes over and above the changes that were in Arthur's patches: Changes affecting current and future time stamps. * America/Eirunepe also changed from ACT (UTC-5) to AMT (UTC-4) on June 24. Changes affecting past time stamps. * For Mauritius, also include the 1982/1983 DST as reported by Steffen Thorsen. * For America/Argentina/San_Luis, redo the history from 1990 through 2000 to match what's in Shanks & Pottenger. The following changes should not affect externally visible behavior. * Redo comments about Brazil to make it clearer about what west Para contains. * Update Brazil comments to mention Decree 6,212 (2007-09-26). * Make comments a bit more concise for Brazil and Mauritius. * Redo comments about Argentina to reflect the fact that San Luis is now separate. * Redo the daylight-saving rules for Berlin in 1945 to make it clearer that these are for the Soviet Zone, not for Berlin in general. * Redo Bahamas rules to make it clearer that the rules after 1975 are the same as the US. * Add comments about time in China from 1949 to 1980. (Thanks to Thomas S. Mullaney for this.) * In tz-link.htm, add mention of daylight-savings-time.info, update links to Vzic, to efele.net map, and to the NPL. =================================================================== RCS file: RCS/africa,v retrieving revision 2008.3 retrieving revision 2008.3.0.1 diff -pu -r2008.3 -r2008.3.0.1 --- africa 2008/05/19 21:48:03 2008.3 +++ africa 2008/07/07 07:35:01 2008.3.0.1 @@ -1,4 +1,4 @@ -# @(#)africa 8.11 +# @(#)africa 8.12 # <pre> # This data is by no means authoritative; if you think you know better, @@ -387,9 +387,33 @@ Zone Africa/Nouakchott -1:03:48 - LMT 19 0:00 - GMT # Mauritius + +# From Steffen Thorsen (2008-06-25): +# Mauritius plans to observe DST from 2008-11-01 to 2009-03-31 on a trial +# basis.... +# It seems that Mauritius observed daylight saving time from 1982-10-10 to +# 1983-03-20 as well, but that was not successful.... +# http://www.timeanddate.com/news/time/mauritius-daylight-saving-time.html +# +# From Alex Krivenyshev (2008-06-25): +# http://economicdevelopment.gov.mu/portal/site/Mainhomepage/menuitem.a42b2412... +# +# From Arthur David Olson (2008-06-30): +# The www.timeanddate.com article cited by Steffen Thorsen notes that "A +# final decision has yet to be made on the times that daylight saving +# would begin and end on these dates."
