Dirk Losch's heads-up about Egypt suggests it's time to push out a new version, since the tz data will become incorrect for Egypt on September 7 and lots of people are on vacation now. Here's a proposed patch containing all the patches I've accumulated recently. Sorry, I don't recollect some of the contributors and gmane seems to be down so I can't access this data easily; my apologies if I've omitted your name. * Egypt switches the September 7, not September 28. Thanks to Dirk Losch for this. * Daviess, Dubous, Knox, Martin, and Pike Counties, Indiana, switch from central to eastern time in November. This results in a zone split, and a new entry America/Tell_City is created for Perry County, which does not switch zones in November. * South Australia, Tasmania, Victoria, and New South Wales are changing their DST rules effective next year. DST will end the first Sunday in April at 03:00 and start the first Sunday in October at 03:00. Lord Howe Island has a similar change. * Several Antarctic station's rules weren't properly updated to account for this year's change to the New Zealand daylight saving rules. * In zone.tab (sorry, I don't recall who sent in these changes): ** Dumont-d'Urville is a station, not a base. ** Correct the coordinates for Aruba, Cambridge Bay, London, Johnston. ** Give alternate spellings for Zaporozhye. * Add spelling notes for Kiev, Uzhgorod, Zaporozhye. (Sorry, I forgot who wrote this.) * Identify American time zone boundaries more carefully. (Sorry, I forgot who sent this in.) * Improve historical notes for Howland, Baker, and Jarvis. * Fix an HTML typo in tz-art.htm. * In tz-link.htm: ** Add Wikipedia references for "public domain", "JavaScript", "Java". ** Don't claim HP-UX uses the Olson database; it has its own. ** Remove reference to IRIX, which is no longer sold. ** Mention the PublicDomain C# library. ** The CIA moved its time zone map. Again. ** Mention the efele.net map. ** Clarify what happens in international waters. =================================================================== RCS file: RCS/africa,v retrieving revision 2007.6 retrieving revision 2007.6.0.1 diff -pu -r2007.6 -r2007.6.0.1 --- africa 2007/05/07 14:46:15 2007.6 +++ africa 2007/08/17 20:51:39 2007.6.0.1 @@ -218,7 +218,15 @@ Rule Egypt 1995 2005 -
