Milestone "time elapsed" makes little sense.
https://gitlab.com/gitlab-org/gitlab-ce/milestones/23 shows "54% time elapsed". I'm assuming that's from the creation date until the expiration date of the milestone, but with a milestone for every release on the 22nd that makes no sense. Milestones should have a start date, which in our case would be the date of the previous release, or this time elapsed should go.
