Shouldn't there be two minute hands if you add LA and India (PST and IST)? The minutes are offset by 30 mins in this scenario.

Came here looking for a comment suggesting these discrepancies. I was not disappointed.

Hey meaniehead... I added offsets to the hour hands for +30 and +45 timezones!
Can anyone recommend a book that discusses in depth all the peculiarities of timekeeping, time zones, historical efforts for measuring time, etc.? I would love to read something like that and I feel that there are many stories to be told.
It’s a long post, not a book but still a great resource on this topic:

You can see this by the position of the hour hands. The minute hand is “just” a convenience.
Another one for Nepal, they have an offset of 45 mins.
It appears the minute hand only reflects local time.

When I add time zones with fractional-hour offsets, the hour hand for those zones is at the appropriate angle within the indicated hour.

Also, Newfoundland and Labrador (GMT -3:30)
And South Australia
