> The required accuracy (Tables 1 and 2 in that document)

no, Tables 1 and 2 say divergence, not accuracy

accuracy is a mix of both granularity and divergence

regardless, your statement before:

> The regulatory requirement you linked (and other typical requirements from regulators) allows a tolerance of one second, so it doesn't call for this kind of technology.

is not true

> accuracy is a mix of both granularity and divergence

I respectfully disagree.

In context, "granularity" is nothing more than a resolution constraint on reported timestamps. Its inclusion adjacent to the specified "divergence from UTC" is a function of market manipulation surveillance objectives as discussed in preamble item (2), and really doesn't have anything to do with accuracy proper.
