Narrative:

Aircraft was delayed on the gate due to maintenance for over 1 hour 30 min past scheduled departure time. We received our clearance via pre departure clearance with a void time of XX55Z. We pushed back at XX05Z and off the ground at XX15Z. Departure control asked if we had a clearance, we said we did. He said he had no strip on us. Then I realized I forgot to update my clearance void time. The controller re-entered our clearance and we were on our way. I have no input except that I failed to update my void time due to being in a big hurry to get the flight moving.
