What I left unsaid was that the use of extra subsecond resolution is optional. I do not see any reason for *us* to create commits with subsecond resolution when we are writing native commits. Only when the end users and/or import tools tell us to. If you assume all foreign SCM you care about have at least one second resolution, you would be fine.

Having said all that, given that this, if implemented, would not be used by us but only for recording other people's times, and that the set of meta information we record in our history will never be superset of everybody else's anyway, I do not see much point in supporting subsecond timestamps in the first place.
