Re: Millisecond precision in timestamps?

fsck_ident() in fsck.c rejects anything but " [1-9][0-9]* " after
the author and committer ident (i.e. the timestamp has to be
integral number of seconds since the epoch, not before it, nor
with fractional seconds).

Is this architecturally significant?  It sounds like another
implementation detail.

No.

If you create a commit object that violatse it and have 47 million
existing users pull such a history, they not be able to use such a
history with the version of Git they have.  Don't go there.

As somebody else mentioned, in distributed environment millisecond
timestamps won't have much meaning, so it looks like a very low
priority to me from Git's perspective.
