Well, I was about to advise that time zones change on the hour, not the half hour, but I just learned that India is one of a few countries with an offset time zone, so it really is just a 1/2 hour difference between Pakistan and India.
India seems like a pretty large country geographically to squeeze into one shortened time zone, but I guess Nepal is even stranger. Apparently it's 15 minutes behind its eastern time zone neighbor, but 45 minutes ahead of its western time zone neighbor. :shock:
And here I thought Daylight Savings was bothersome.
You learn something
new every day.
I was going to suggest a re-write of "As you move west across the globe, you lose an hour for every new time zone", but I guess that's not strictly true.
Tufguy, note that you added time while moving west, instead of subtracting. You'd have to move east to gain time.
