If I'm following correctly then:

1) Under old system there where preset two hour slots over a day period, 
where the period was say 8:00 to 16:00

2) You now want to allow user defined two hour slots over the same 
period, where a slot can't start before 8:00 or end after 16:00.

3) First to file gets the slot.

4) Because of turn around considerations a user can't pick up the 
remaining hour of an overlap. As example in the case of time slots of 
10:00 - 12:00 and 11:00 - 13:00 for a particular plane where the second 
slot was the later one filed the user can't get 12:00 - 13:00.
