Its a RFS date these can slide. You could always check with reseller, such as vivaciti, titan, I only mention these as they sell tt product as others don't for me and i'm not to far away from you in Newtown. You could phone TT direct they might/or not know, depending on who you get.
You could check on the TT until recently however when i last checked TT had removed this for non customers.
