I think DUT1 changes on month boundaries.  When I was last at
WWVH there was a note on the bullboard specifying what the DUT1
would change to at the end of the then-current month.  So they
probably know it now, its being December and all that.  And I'm
pretty sure it won't change between now and then.

My intent (in case the between-the-lines writing was muddy) is to
make a two-track audio tape at the time of Leap with the
broadcast timecode from 15 MHz on one channel and my prototype
TCG's output on the other.  I'd like to know what the DUT1 should
change to in order to get my code right.

Of course, having seen the hardware, I know they need to manually
crank a thumbwheel switch to change what they send.  Mine will
change it automagically.  In the past, the transmitted DUT1
typically has changed a few minutes after the leap.  So for those
few minutes it has been _WAY_ off, having not moved from -.5 to
+.5 (or whatever) with the insertion of the leap.
