I have a recollection that Dave says that the clock needs to be within
60-odd years of the correct date, and this was after he did some work to
expand this from the previous limit of 30-odd years.

I forget the exact number offhand.

It is possible there is an arithmetic overflow or signed/unsigned problem
somewhere.

I'd love to see this documented somewhere easy to find and also get a test
case going.
