a half hour
Did you know that Newfoundland is in a half hour time zone?
Newfoundland is the only place in North America that wears a half hour difference from the next timezone. It's a half hour later than Atlantic time, an hour and a half later than my home Eastern time zone.
Really? Three and a half hours by sun dial?
from http://www.timeanddate.com/time/time-zones-interesting.html: Newfoundland does not follow the rest of Canada in keeping time because of two main reasons. First, while Newfoundland is located in the UTC-4 timezone, it is exactly three and a half hours from UTC as measured by a sun dial. Second, the legislation that decided the time offset for the province was passed in 1935, 14 years before Newfoundland joined Canada in 1949.
