I did not know that one can store nanoseconds.

Yes. After reading Philip's post and your post, it makes zero
sense to be setting the mtimes.

Here is where I admit I feel like a quick hack. Of course
there must be a clearly defined format.

True. I figured that if users wanted a mtime, they certainly might want
to also know when it (file or directory) was first added or committed or

That's definitely true. Perhaps (possibly a quick thought hack) if
during an Add, a commit or an import, the directory's contents are
also included (unless specified in ignore item) so would an
add-mtime, commit-mtime or import-mtime be set on the directory
and it applies to its contents? Further additional files or
subdirectories have their mtimes added in the usual fashion.
(Am I making any sense here?)

Well, it was my thought that the users might want statistical
information on the original add, commit, import, merge, etc..
mtimes on their files/directories.
Thanks for the comments.
