Granted, but moving an entire border to the middle of city takes much more than just "one crazy politician"

Anyway in such cases new names show up:"Northern Nicosia", "West Berlin" and problem solved.

A fork for the time-zone database?

As I said, what about Kansas City? That's got a state border running through the middle of it. That doesn't need resetting borders, all it takes is one state government changing time zone ...

Even Britain/London is a mess. Which London? And, just like New York City is not the capital of New York State, the capital of Britain is not the City of London, it's the City of Westminster about two miles away.

Borders might not move, but towns and cities do - another favourite example of mine is Dover, where the town centre is in the village of Charlton, about two miles from away from Dover itself (which historically is just Snargate Street, by Western Docks, for those who know the place).

I'm sure pretty much any historic country (which excludes the US, which is why they don't understand these things) will have plenty of examples. All it takes is a river, and then some invading army makes the river the border, and then towns get cut in half, or a bridge is built and towns merge, or or or ...

Cheers,
Wol

I dunno. Even countries newer than the US, like Canada, have examples, some of which involve changes that don't even involve changing the clocks, just the zone. In my (rather old) tzdb copy, Chris Walton says:

# On March 11/2007 most of Canada went onto daylight saving. On March
# 14/2007 I phoned the Resolute Bay hamlet office to do a "time check." I
# talked to somebody that was both knowledgeable and helpful. I was able
# to confirm that Resolute Bay was still operating on UTC-5. It was
# explained to me that Resolute Bay had been on the Eastern Time zone
# (EST) in the winter, and was now back on the Central Time zone (CDT).
# i.e. the time zone had changed twice in the last year but the clocks
# had not moved. The residents had to know which time zone they were in
# so they could follow the correct TV schedule...

(The US has examples of single towns where this was contended, so some residents historically followed one timezone and others followed another. As far as I can tell, *anything*, no matter how ludicrous, has been done somewhere, somehow, by someone where timezones are concerned.)

Exactly why timezones are city based and don't follow state lines.

Was the Kansas metro ever split into more than one timezones? If it ever was, just name the zones after some other cities that were not split.

Yet no one ever felt the need for a Resolute Bay time zone.

Sure but has it ever been a problem finding a(nother) city to name it? Worst case call it west Jerusalem and done.
