Nova Scotia and Northwest Territories have fallen in line with the rest of the Canada. Daylight saving time will be extended by four weeks starting in 2007. Affected zones are: Nova Scotia: America/Halifax America/Glace_Bay North West Territories: America/Yellowknife America/Inuvik We don't need to make any rule changes to TZDATA. All four of the affected zones use the "Canada" rule which has already been updated. Here is a news release which was issued today by the Nova Scotia government: http://www.gov.ns.ca/news/details.asp?id=20060425004 I could not find any reference to the change on the Northwest Territories government web site; the only reference I have is a news story posted on the CBC (Canadian Broadcasting Corporation) web site on April 5: http://www.cbc.ca/north/story/nor-nwt-time-change.html I think we are still waiting to hear from the governments of Newfoundland, Yukon, and Nunavut. -chris
