It says "a minimum of 1 hour after the proposed departure time."
Every place I've ever inquired, they've told me I get two hours.

I think the AIM (see 5-1-11) says that flight plans will stay in the =

computer 1 hour after departure. Also, AIM paragraph 5-1-7 says that: =

Pilots should file IFR flight plans at least 30 minutes prior to =
estimated
time of departure to preclude possible delay in receiving a departure
clearance from ATC.".

There's a lot of good information in that "little" book.

If I file an IFR flight plan 2 hours in advance from departure from a
towered airport and then leave really early or really late:
1. Is the FP normally available to my local tower about half an =
hour
after filing?
2. How long does it remain in the "system" if I get delayed?
