As far as I am aware, all of the main Linux distributions had updates
available to bring the timezone tables up to date. But if systems
aren't being updated on a regular basis, they won't get the new
information. It's possible that those Red Hat machines hadn't had
updates run in some time.
Does it mean I should consider upgrading these 2.2.6 linux kernel boxes?

Joke apart, I would think that in any case, January should not be

Hi:
There's a new Software Defined Radio by RF Space, makers of the SDR-14,
called the SDR-IQ. The two key differences are that the new radio will
tune down to something like 500 Hz (that's NOT kHz, but Hz) and so will
work for LORAN-C and other low end stuff. The -IQ model has a 190 kHz

Pretty unlikely. If you drop a crystal, it will just break and
not work. The only way it could go down 100 Hz is by mass loading.
I don't know how this could happen in a sealed unit.

I had thought of something similar, using a Lissajous pattern, but that
only compares one oscillator against the other.
Once I determine that the XO is indeed locked, then the next step is to
determine the frequency.
But, the first step is to determine that the XO is locked.
Then I'll go looking
Count the number of oscillations between the 1PPS, that will get you 1x10-7 any
