You will get a Null value returned from TIMESTAMPDIFF

  if ( (is_null($MinsSinceMyDateTimeField)) || ($MinsSinceMyDateTimeField > 10) )

$sql = "SELECT *,
		DATE_FORMAT(start_date, '%d/%m/%Y') AS date_start,
		DATE_FORMAT(end_date, '%d/%m/%Y') AS date_end
	FROM project_profile WHERE project_id = $project_id";
