And -- just to quibble a bit, but in a *nice* way -- it would not matter
even if it did contain the "current" date.
The Date field specifies the time of posting.
Signing might take place at any time after that (or even before that.)
So, color me slow. We know for sure that signing happened in the
past. What specific value do we place on how far in the past that
signing occurred? What code do I write to test that specific value and
what do you recommend that a verifier do with such knowledge?
