Does anybody know how many bits of precision are used
on tombstones these days?
Most tombstones are engraved with CNC machines and while I have yet
to see a company advertise it as a competitive parameter, your vital
lack of stats will be engraved with better than 1/50mm precision.
Oh, I was mostly concerned with the bits of precision used for the birth and
death timestamps.
I should think that if you have left instructions with your executor,
they can have any arbitrary number of digits engraved, including an
estimate of uncertainty, if needed. You could even have them estimate
the Allan deviation of the various clocks involved, and have the
requisitite plots engraved as well.
