That's a good summary on your webpage - would have been helpful if I'd
found something like that instead of the lore-filled manuals I managed

Accuracy wise, it should be low ms, provided it's synced. In practical
terms, say if you have a roomful of equipment all flashing LEDs in
some pattern, they will be synchronised and appear to all be flashing

It's really showing its age now that every cellphone and gadget can
have GPS and accurate time for a very low cost.

Will you be writing up PTP (IEEE 1588) next? ;-)
