I have been using PubSubHubbub version 0.4 to retrieve YouTube realtime data. I was going through the PubSubHubbub document to know about hub.lease_seconds
In this document, they didn't mention anything about maximum limit for this parameter.
What is the maximum value that can be given as hub.lease_seconds parameter?
It's 828000 seconds. If you try to give any value larger than 828000 it is simply ignoring it and sets the hub.lease_seconds as 828000.
