I wonder if the cron job should be run every 1/2 hour to catch timezones that are 1/2 hour offsets?

(There are even more than I thought)

I was pretty surprised at that as well when building http://hackertimezone.com. I always assumed it was mostly confined to small island chains and so forth, but there's some world cities in there as well.

my personal favorite is the 45minute offset: http://en.wikipedia.org/wiki/Chatham_Islands#Chathams_Time

@grecy, good question.

It actually still works as expected.

If the time in Pakistan, for example, is 7:00am, then the time in India is 7:30am. The code just checks the hour, which would be 7 in either case.
