The tags are listed in alphanumeric order, but some clients may wish to order the tags by the date they were created. Add a timestamp in the tag info. For annotated/signed tags, the timestamp is the date at which the tag was created. For lightweight tags, the timestamp is set to the committer timestamp, only when the tag is on a commit.
