Template:Unsigned
From IFWiki
After unsigned comments on talk pages, add {{subst:unsigned|Date|Username}}, with details copied from the page's history, e.g. {{subst:unsigned|17:24, 8 January 2022|ExampleUser}}, to add a signature like as if the user had typed ~~~~, e.g. ExampleUser (talk) 17:24, 8 January 2022 (UTC). It adds "(UTC)" to the end so check the time is UTC.
