I just read in Wikipedia that Glace Bay, Nova Scotia, Canada existed only from 1901 to 1995. The government of Glace Bay was dissolved on 1 Aug 1995 when eight municipalities, including Glace Bay, were consolidated to form Cape Breton (a.k.a. CBRM, short for Cape Breton Regional Municipality), which is currently the second-most populous municipality in Nova Scotia after Halifax. Wikipedia shows Cape Breton’s coordinates as 46° 9’ north latitude by 60° 10’ west longitude. That longitude corresponds to a local mean time of UTC-4:00:40.
