The strip outfall from our printer should still have the latest EOBT to which you are working. This may be the original scheduled time, or if your company are on the ball and aware well in advance that the flight will be late (hence DLA messag ehas been sent), the time that they have filed as your likely EOBT.
It's all got considerably more complicated, with changes to EOBT updates and now changes to the way the information is updated within NATS' computer. Why were those changes made to NATS' system? Who knows - probably someone had a bright idea and now we're having to deal with the knock-on effects
