As already mentioned, the time zones in America do not strictly adhere to the 7.5 degrees on either side of the central meridian, but follow convenient political boundaries. Be aware that Newfoundland has a 3.5 hour offset from Greenwich. The central meridian would be 52.5°. Two islands quite close to Newfoundland maintain an even offset of of 3 hours. They are St. Pierre and Miquelon. As for the rest of the world there are a number of other half hour offsets. Among them are India, Iran, and Afghanistan. If that's not enough, Nepal has an offset of 5 hours 40 minutes. There is a world time zone map that is not easy to read at: http://aa.usno.navy.mil/faq/docs/world_tzones.html Bob Terwilliger co-author, with Fred Sawyer, of The Dialist's Companion.
