Change 'master@noon' syntax to 'master@{noon}'.
Its ambiguous to parse "master@2006-05-17 18:30:foo" when foo is meant as a file name and ":30" is meant as 30 minutes past 6 pm. Therefore all date specifications in a sha1 expression must now appear within brackets and the ':' splitter used for the path name in a sha1 expression ignores ':' appearing within brackets.
