It occurred in the year 4004 B.C. DRUMMOND That's Bishop Usher's opinion. BRADY It's not an opinion. It is literal fact, which the good Bishop arrived at through careful computation of the ages of the prophets as set down in the Old Testament. In fact, he determined that the Lord began the Creation on the 23rd of October in the Year 4004 B.C. at -- uh, at 9 A.M.! DRUMMOND That Eastern Standard Time? (Laughter) Or Rocky Mountain Time? (More laughter) It wasn't daylight-saving time, was it? Because the Lord didn't make the sun until the fourth day! BRADY (Fidgeting) That is correct. DRUMMOND (Sharply) The first day. Was it a twenty-four-hour day? BRADY The Bible says it was a day. DRUMMOND There wasn't any sun. How do you know how long it was? BRADY (Determined) The Bible says it was a day. DRUMMOND A normal day, a literal day, a twenty-four-hour day?

In the (Toronto) Globe and Mail for Saturday, 1955-09-24, in the bottom right corner of page 1, it says that Toronto will return to standard time at 2 am Sunday morning (which agrees with the database), and that: The one-hour setback will go into effect throughout most of Ontario, except in areas like Windsor which remains on standard time all year. Windsor is, of course, a lot larger than Nipigon. I only came across this incidentally. I don't know if Windsor began observing DST when Detroit did, or in 1974, or on some other date.

Update time zone of the United States-Mexico border
by Ing. Obed Javier March 16, 2010

March 16, 2010

Hello, I'm using the google translator, I apologize if there is a misspelling; I know how to update the time zone (or to do ubuntu) to the border towns of Mexico with the United States and took effect on daylight saving time and yet time has not changed. In border cities, daylight saving time begins the second Sunday in March, and the rest of Mexico, the first Sunday in April. As a reference, put the story that supports this change: http://www.elmananarey.com/diario/noticia/tamaulipas/noticias/adelanta_fron… or (in english): http://translate.google.com/translate?js=y&prev=_t&hl=es&ie=UTF-8&layout=1&…

Updated efele.net/tz maps
by Eric Muller March 14, 2010

March 14, 2010

I have updated the maps of the TZ timezones presented at <http://efele.net/maps/tz>: - in sync with 2010e: introduction of America/Matamoros, America/Ojinaga, America/Santa_Isabel - the Kuril islands are now in Asia/Magadan rather than Asia/Sakhalin (thanks to Tobias Conradi for noticing the error) As a result, the Russia and world data files have changed. The other data files are identical. Eric.
