Profile edit : member since

Hello, is there a way to the registration date into the member’s profile so it would read, “Member since 2015” below their avatar? I have this code that is supposed to call that :

<?php
	global $bp;
	$currentuser = get_userdata( $bp->displayed_user->id );
	$joined= date('F jS, Y', strtotime($currentuser ->user_registered));
	echo $joined;
	?>

It should be placed in the theme/buddypress/bp-templates/bp-legacy/buddypress/members/single/member-header.php file. I’ve tried to do that with no effect. I thought I would ask about that capability here. Thank you!
