Here is the latest set of proposed changes for Egypt, Syria, and Uruguay. This supersedes the two messages I sent out earlier on this subject in <http://article.gmane.org/gmane.comp.time.tz/1224> and <http://article.gmane.org/gmane.comp.time.tz/1221>. I'd like to thank Steffen Thorsen, Oscar van Vlijmen, and Jesper Norgaard Welen for reading and correcting the earlier messages. This change affects time stamps within the next 48 hours in Egypt and Syria, so people interested in up-to-date correctness in those regions need to apply this patch soon. =================================================================== RCS file: RCS/africa,v retrieving revision 2006.12 retrieving revision 2006.12.0.1 diff -pu -r2006.12 -r2006.12.0.1 --- africa 2006/09/18 16:58:11 2006.12 +++ africa 2006/09/20 19:35:29 2006.12.0.1 @@ -212,35 +212,13 @@ Rule Egypt 1990 1994 - May 1 1:00 1:00 # Go with IATA starting in 1995, except correct 1995 entry from 09-30 to 09-29.
