On: A clock that can detect tiny shifts in the flow of time itself

[droopybuns]

If we designed houses around planck lengths as the unit of measurement, we'd get nothing done.

It's not that timekeeping gets meaningless- it just means that there is a threshold where the variability of unsynchronized clocks disrupts certain highly precise problems.

I was looking for someone to make a comment like this. I also felt that it simply meant that the last few digits were less meaningful for applications such as sync, but it definitely doesn't mean that that's the case for all the digits.
