Hello, I found the following article in a Brazilian newspaper (in Portuguese): http://www.agencialusa.com.br/index.php?iden=9926 From what I can understand it says that Venezuela will go from the "-4 hour GMT" to the "GMT-4,5 hour time zone" on 2008-01-01. I am not sure if they will revert at midnight or at half an hour after midnight (in the old time zone). It is a little bit confusing, because it says many places that they will advance their clocks by 30 minutes (from UTC-4), which technically would mean that they would enter UTC-3:30. However, it says that meridian 66 will determine the new time zone, and since 66/15=4,4 hours, *and* they have been in the 4,5-hour time zone before, I think it is likely that they are going back to that time zone. Best regards, Steffen
