Good suggestion.

This was introduced in 116eb3ab (parse_date(): allow ancient
git-timestamp, 2012-02-02) and 2c733fb2 (parse_date(): '@' prefix
forces git-timestamp, 2012-02-02) to allow specifying "ancient"
timestamps (like 0 +0000) without conflicting with YYYYMMDD date
formats.  I do not think neither commit added documentation for this
'@' prefix, and Documentation/date-formats would be an excellent
place to do so.

Care to whip up a patch?

Thanks.
