There is an unpaved gravel lot on a hill next to Ithaca Falls. I always park there when I visit the falls. I've stayed for up to an hour with no trouble. The falls are only a few steps from the parking lot so you probably won't need more than an hour anyway. I did not see any postings about a 1 hour limit the last two times I was there but do pay attention to signage. I got a ticket where I parked near the entrance to Cascadilla Gorge.
Thank you... it's just some place different
