Template:unsigned2/documentation

Usage
This template takes three positional parameters:


 * 1) (required) a timestamp indicating when the comment was posted.
 * 2) (optional) the username of the user who posted the comment.
 * 3) (optional) the time zone; the default is UTC.

If the user has an IP address rather than a username, then may be preferable: it does not link to the IP's user-page.
