Just in case anyone else thinks about doing this: don't!
First I did it as a set of expansions in exim. That slowed things
down so much that when I turned on -d+expand, the other side of my
application testing would time-out, which was a good exercise.
So, I boldly went in and added an expansion item to the exim source.
That turned out to be fun because the source is so easy to read and
modify. But then I realized that my algorithm isn't very good, when
daylight savings time comes and goes, I simply can't know for sure.
But apparently, PHP has a function that does it.
So, I put the whole $h_Date: in the filename and let the
user-interface programmer run the PHP function over it.
