Living on the boundary between time zones?

Question

If there is a very definite border where you cross from one time zone to the next, it's possible to build a house on the divide, right? And if so, how would time inside the house be measured? An hour earlier on the west side of the house, an hour later on the east side?

Or what if you had a city straddling the line between time zones? Are there any that you know of?

Sorry, sort of a sloppy, rambling question. It's just something I wonder about.

Answer 1

While time zones theoretically should be straight lines, the political jurisdictions alter them slightly so they will bend to meet actual habitation patterns or jurisdictional lines.  A good example is China - it should fall into more than one time zone, but the authorities have seen fit to deem it as falling completely into one time zone.
