Perhaps I should have pointed this out six months ago, but bzr presents
the same issue as git does re: commit timestamps vs. authorship timestamps.
The authorship timestamp is what's displayed by "bzr log" in the
"timestamp:" field; the commit timestamp is the decimal string in the
middle of the revision-id.
I gather that what you've been using thus far in the conversion from bzr
is the *authorship* timestamps, not the commit-timestamps.
Sorry--I mostly just wasn't paying close enough attention six months ago
to point out all of the angles of this issue...; though I *did* raise
this "ambiguity of reference by timestamp" issue at that time--and thought
that you'd given an ACK with a statement you were going to fix it by using
"#{sequence-number}" suffixes to distingiush between multiple distinct
items in the same "{ISO-date}!{email-address}" hashbucket:

https://lists.gnu.org/archive/html/emacs-devel/2014-01/msg01113.html
(that first link is your response; the second is my message--which
included an example of why the "same timestamps, different commit-
objects" situation might exist in a repository)

"'tis an ill wind that blows no minds."
