What is the longest possible delay between GIF frames?

Question

I've searched and found no answer, and the GIF specification is over my head. What is the longest possible delay between frames in a GIF animation?

Answer 1

Your reference says the delays are 2 byte unsigned integers and the unit is 100ths of a second. So the max duration in seconds would be (2^16-1)/100 = 65535/100 = 655.35s or about 11 minutes.
