Narrative:

I phoned ny TRACON from hwv, requesting a void time of 15 mins on an IFR clearance to msv. I only got about 10, but I was ready to depart. However, the controller did not say, 'time now...,' as they do in the air when giving an efc time. Even though it was my responsibility, I neglected to ask, probably because I had no idea TRACON would give a pilot less than 10 mins to depart! Thus my watch seemed correct and I had no reason to question whether it was correctly set. I was off the ground in 6 mins. After departure I made contact with ATC on the departure frequency and was told that I was late. I then asked for the time, since I had checked my watch before takeoff, which incidentally matched exactly the time on the aircraft clock! The time they gave me indicated that my watch and the aircraft clock were both a few mins slow. I apologized and was cleared to proceed with the flight. Although the entire incident was flown in VFR conditions, I learned always to check the time on a void time clearance.

Original NASA ASRS Text

Title: PLT REQUESTED DEP TIME AND WAS GIVEN A LIFTOFF TIME OF LESS THAN 10 MINUTES. TKOF TIME WAS APPROX 6 MINUTES, BUT IN AIR THE N90 CTLR ADVISED PLT WAS LATE IN TKOF TIME.

Narrative: I PHONED NY TRACON FROM HWV, REQUESTING A VOID TIME OF 15 MINS ON AN IFR CLRNC TO MSV. I ONLY GOT ABOUT 10, BUT I WAS READY TO DEPART. HOWEVER, THE CTLR DID NOT SAY, 'TIME NOW...,' AS THEY DO IN THE AIR WHEN GIVING AN EFC TIME. EVEN THOUGH IT WAS MY RESPONSIBILITY, I NEGLECTED TO ASK, PROBABLY BECAUSE I HAD NO IDEA TRACON WOULD GIVE A PLT LESS THAN 10 MINS TO DEPART! THUS MY WATCH SEEMED CORRECT AND I HAD NO REASON TO QUESTION WHETHER IT WAS CORRECTLY SET. I WAS OFF THE GND IN 6 MINS. AFTER DEP I MADE CONTACT WITH ATC ON THE DEP FREQ AND WAS TOLD THAT I WAS LATE. I THEN ASKED FOR THE TIME, SINCE I HAD CHKED MY WATCH BEFORE TKOF, WHICH INCIDENTALLY MATCHED EXACTLY THE TIME ON THE ACFT CLOCK! THE TIME THEY GAVE ME INDICATED THAT MY WATCH AND THE ACFT CLOCK WERE BOTH A FEW MINS SLOW. I APOLOGIZED AND WAS CLRED TO PROCEED WITH THE FLT. ALTHOUGH THE ENTIRE INCIDENT WAS FLOWN IN VFR CONDITIONS, I LEARNED ALWAYS TO CHK THE TIME ON A VOID TIME CLRNC.
