Most likely you'd get similar time if you run `bzr branches` in your
location.

live head -- exists in the branch as branch tip.

dead head -- tip revision not in the branch.

Dead head created by `bzr uncommit`, `bzr merge && bzr revert` or `bzr
pull --overwrite` (losing your local history). The purpose of `heads`
command is to be able to find revision ids for lost revisions.
