If you pick up a clearance but do not get a clearance void time, how long is it good for?
I have received a clearance from ground (at towered field) but had to delay my departure (30 minutes to 1 hour) due to WX. I understand ATC occasionally will issue clearances upon landing for subsequent flights the same day made by aircraft transiting a field.
So, for towered or untowered fields, assuming no void time is received how long before departure may one get a clearance and it still be valid?
