That never quite solves the auto-timezone/DST issue that OP wants to have work, though, does it?

If I am interpreting their request correctly, they want a wall clock that knows where it is -- and also knows what localtime is in that position on the globe.

GPS (plus some hairy lookup tables) can accomplish that.

DHCP has an option for timezone information. Not a lot of people fill it out, though.
