Display a beautiful, human-readable, comment time:

function smk_get_comment_time( $comment_id = 0 ){
	return sprintf( 
		_x( '%s ago', 'Human-readable time', 'text-domain' ), 
		human_time_diff( 
			get_comment_date( 'U', $comment_id ), 
			current_time( 'timestamp' ) 
		) 
	);
}

When called it will convert the time and return something like:

"1 min ago", "3 mins ago", "17 hours ago", "7 days ago", "2 weeks ago", etc....
