it's hard to give a good answer, since i don't
know what the goal is.

of course on a worm filesystem, you could say that each
time a file is modified after it has made it to the worm, it
becomes a brand new file.  though the qid.path doesn't
track this view.  the create time would then differ
from the mtime by as most the time between dumps.

history doesn't give creation times.  it gives the last mtime
before the first dump of the file.  the file could be deleted
and recreated many times and you'd never know.  (unless
you were to peek at the qid.path.)

but then again, history might be exactly what you're
looking for.  it usually is for me.
