Hi, I recently heard that from the moment of touching in, I have 2
hours to touch out, otherwise I will pay the penalty for not touching
out. Is that true?

I heard they upped it to 3 hours even, but I'm actually not sure about
that.

Within the last month, I was travelling round the network with no need
to leave it. A duration of 2.15 attracted an exceptional charge; 1.57
did not. I think the limit is 2 hours which was what was quoted by the
Oyster telephone help line. A long time ago, I saw documentation of such
limits but such documentation seems absent now.
