I wanted to get date information in RFC2822 format out of a tag using
git-for-each-ref; but there was no way to specify that. This patch
addresses that omission by adding a --dateformat option.
For example (I'm in BST, +0100 at present):
$ git-for-each-ref --dateformat=normal --format='%(taggerdate)' refs/tags/v1.5.2
Sun May 20 00:30:42 2007 -0700
$ git-for-each-ref --dateformat=relative --format='%(taggerdate)' refs/tags/v1.5.2
4 months ago
$ git-for-each-ref --dateformat=short --format='%(taggerdate)' refs/tags/v1.5.2
2007-05-20
$ git-for-each-ref --dateformat=local --format='%(taggerdate)' refs/tags/v1.5.2
Sun May 20 08:30:42 2007
$ git-for-each-ref --dateformat=iso8601 --format='%(taggerdate)' refs/tags/v1.5.2
2007-05-20 00:30:42 -0700
$ git-for-each-ref --dateformat=rfc2822 --format='%(taggerdate)' refs/tags/v1.5.2
Sun, 20 May 2007 00:30:42 -0700
The default is to use 'normal', which leaves existing behaviour
unchanged.
