It's not in the system because there is no new flight, your flight is just delayed exactly 24 hours now.The e-mail says rebooked, but its just confirmation of the same flight you were already on, only delayed. The ground staff at the airport will sort out your onward flight to ATH, or you can call BA back and tell them to look at the new scheduled times for your existing flight and they will see that it was scheduled to arrive LHR 13:45 local on the 10th and is now planned to arrive at 13:00 local on the 11th.
