When I request my IFR flight form the controller at smaller airports the controller says clearence void 30 minutes from now.
What does it mean, and what do i have to do?
Thanks

You have to take off in less than 30 minutes.

Clearance Void Times. A pilot may receive a clearance, when operating from an airport without a control tower, which contains a provision for the clearance to be void if not airborne by a specific time. A pilot who does not depart prior to the clearance void time must advise ATC as soon as possible of their intentions. ATC will normally advise the pilot of the time allotted to notify ATC that the aircraft did not depart prior to the clearance void time. This time cannot exceed 30 minutes. Failure of an aircraft to contact ATC within 30 minutes after the clearance void time will result in the aircraft being considered overdue and search and rescue procedures initiated.

Thank You CRJ

yeah thats exactly what cleareance void time means,,for a nonpilot it means that the airpace will be protected for you during that window time that you have to take off,,if you dont take off during that time , that airpace could and will be used for somebody else..

Pertains *ONLY* to IFR traffic. If weather is VFR, there can be any number of VFR airplanes operating in/on/around that airport, ATC's not gonna' be talking to 'em, and they don't have to talk to anybody either.
