How doable would it be for mains electrical supply to have the time encoded into it, and for a device with a clock to automatically synch to the time on power up?

It's doable locally, with say an X10 system. But you'd have to have an X10 clock talking to some other X10 source that maintains the time, but that would of course be pretty stupid in most cases. Far easier to just have battery or supercap backup, or utilise one of several forms of wireless time standards.
On a larger grid scale it's also technically possible in theory, but fairly difficult to do in practice.

Depends on what application/cost, but what about a small GPS module that produces 1 microsecond pulses synchronized to GPS clocks from the satellites?

Sounds just as pheasable as that 'Internet Over Power' drive a few years back.
Thankfully, that idea went the same way as last night's turkey.
