Less simple and stupid than I thought, but I think I have a fix. It is
not about December specifically, but about the date being in the future.
The first patch is a cleanup to help us more accurately test the bug;
the interesting bits are in the second one.

  [1/2]: pass TIME_DATE_NOW to approxidate future-check
  [2/2]: approxidate: allow ISO-like dates far in the future
