Narrative:

On feb/tue/03, at about XA20 local time, I had received an IFR clearance from a controller at portland, or. I was on the ground at vuo, holding short runway 26. I was given a clearance void time by the controller, and was advised to contact portland departure, and was given a frequency. On the ground at pearson field, there is a sign that instructs departing traffic to contact portland tower on 119.0 before takeoff. I contacted the tower on 119.0 and advised them that I was ready for takeoff on an IFR flight to spokane, wa. He advised me I need not talk to tower, I needed to contact departure. Pearson field is an uncontrolled airport within portland's class D airspace. By the time I took off, I was advised by the controller that I had passed my clearance void time by about 1 min. I was advised that other traffic had been rerted because of the incident. In my confusion on who I needed to talk to prior to departure, I exceeded my clearance void time. I apologized to the controller when he advised me of my error.
