This template should be used when users do not sign their posts in talk pages. It allows quick copying of the date/time and user from article histories to be used with this template. It is a slightly improved version of {{unsigned}} in that it assumes the first parameter is a date/time.
Usage:
{{SUBST:unsigned2|date/time|username}}where "date/time" is the date and time of the post and "username" is the name of the user who did not sign their post.
