Hmmm...I wonder why they call them "Atomic Clocks?"  Other than being
made of atoms like everything else, there is nothing "atomic" about any
of them.  All the atomic things are in Ft. Collins, Hawaii, and on GPS
spaceships.  I think my clock (which I won at the radio club raffle)
syncs to WWVB on 60 KHz, which I can hear on the left-coast at night,
but not in the daytime.

I volunteer at the Blood Center, and since the FDA requires that they
keep a series of times for each of the various blood donation steps for
each donor, they got us three "Atomic Clocks," two Sony's and a Seiko,
so all the times would be consistent.  My job was to hang them on the
walls, and when they were laying together on the table, I noticed that
they all differed from each other by as much as 10 seconds.  I took in
my K2, and they all differed from WWV too.  So much for "atomic time,"
my Pulsar watch does better than that.
