That's some odd code you have there.
For starters, max is a local variable and it is declared inside the foreach loop - so it's scope is limited to that loop: it cannot be accessed outside the loop, so it's pretty much useless.
Then there is the loop itself: that's useless as well, because your method will always return the same value - the last item in the input collection.
Then there is the linq code: why are you sorting your collection each time round the loop? The list can't change inside the loop (or you'd get an "collection modified" error at runtime) so the order is always the same.
Then there is the Max call - that is also useless as it will always return the same value since the collection still can't change inside the loop!

Then there is the error you have noticed: and that's because Max uses IComparable to work out the order of values, and your class TheQFromDB doesn't implement IComparable so Max can't compare any items to have any idea what is the maximum.
Probably what you want is
... input.Max(s => s.SecondsDiff);
But that's just guesswork given that I know nothing about your classes or what that code is actually trying to do...
