Where can I find definitive documentation on all the date formats / expressions I'm allowed to use in e.g. HEAD@{datespec}?
For example, I just discovered I'm allowed to say not only yesterday (documented in git-revisions doc) but also e.g. last.monday.morning. How do I learn that, and all forms of legal date expression that can go here?
(It's not in the git-revisions doc. It's not in the git-log doc; I see that it tells me I can receive a relative date, but it doesn't tell me all the ways to say a relative date.)
