Finite limits in time representations are a fact of life in popular
operating systems, so there's always going to be a value that's just
one incy-wincy-teeny-weeny second on the wrong side of the
limit. Erlang just happens to have chosen an 'interesting' limit.

I don't recall ever seeing a bignum time representation in Erlang,
though there's bound to be a LISP one.

The only way I know of is to remember which file you downloaded. I
don't think the system keeps track of the patch level.

"some OTP person". I guess that's slightly better than being a piece
of "human capital". If you're lucky, someone might help you debug the
problem---there are still a few steps to making it easily reproduceable.
