This adds the options "--since=date" and "--before=date" to git-rev-parse, which knows how to translate them into seconds since the epoch for git-rev-list. With this, you can do git log --since="2 weeks ago" or git log --until=yesterday to show the commits that have happened in the last two weeks or are older than 24 hours, respectively. The flags "--after=" and "--before" are synonyms for --since and --until, and you can combine them, so git log --after="Aug 5" --before="Aug 10" is a valid (but strange) thing to do.
