I've been messing a lot with time zones lately, planning my trips to South Africa, Spain, and Denmark, along with flight connections through other countries, and trying to be sure that I correctly map the local times people tell me with the Eastern times I need to enter in my Outlook calendar. As part of that I found a neat time zone map at http://www.travel.com.hk/region/timezone.htm. Now time zone maps are not exactly hard to come by, but this one gave me some interesting insight.
Until I found this map I believed, in a vague never-bothered-to-check way, that Newfoundland was the only place whose time zones differered by half an hour rather than an hour from the neighbouring zones:
But this map uses that hash pattern to indicate the not-an-hour timezones, and so for the first time I noticed there are other places that do this too:
It's all over the place! But I wonder if people on the other side of the world would get the Canadian joke: The World Will End at Midnight! 12:30 in Newfoundland.
