Narrative:

Received clearance with a void time, and an off time. I did not have my watch on me. Time now XA50, time off XB00, void XB05. Performed run-up and takeoff. Pvd control informed me after establishing communications that I was 3 mins early of my off time. Luckily, there was no conflicting aircraft. Next time I'll make sure I bring my watch!
