Merge branch 'commit_time_timezone' into 'master'

Fix commit time being displayed in the wrong timezone in some cases

This MR makes sure that the displayed commit date is shown in the timezone that's configured in the gitlab.yml.
Before it was possible that the `committed_date` of a commit would display different values on the dashboard and the commit page.

fixes gitlab-org/gitlab-ce#1278
