Hi You can have a surveyor come out and locate your gizmo to sub one inch accuracy for a lot less than a clock trip costs. A one meter ( or 3 ns) error would be pretty large these days. Both have been demonstrated / proven so often that they aren't really open to challenge.
The total error is a sum of lots of things. Location and time of day are the easy stuff...
