Hmmm...bad diagnosis on my part.

(It's somewhat unusual for the developer's side of such a line to be
treated wrongly, and the other side correctly, so it didn't occur to me!
But the code is somewhat easy to visualize, particularly since I've
produced two different Frontier scripts for day of the week, one of which
messes up Jan 1 and Jan 2 1904, and the other messes up about 5 days in
February, 2040, for much the same reason.  I use the former script, rather
than dealing with the slowdown which fixing it would cause.)
