I'm trying to code a negation wrapper plugin right now, so every hammer
I see sort of looks like a plugin wrapper. But here goes...

There is really no reason why a plugin couldn't understand time. But
none of us have enough time as is. A single wrapper could be defined to
take lists of time periods and arguments. A little kludgey, but it
probably can be made to work.

Now it's time for people to call me crazy...
