[time-nuts] Double-Oven Thunderbolt on Ebay

I'm measuring my pair of eBay -60158s right now and will post some
results probably after the weekend.  I've never seen the -60268s.

One thing to note -- good phase noise and good ADEV don't necessarily go
together.  Case in point is the -60158s are spec'd at 1x10e-12 at 1
second, which is better than most of the 10811A variants, but the phase
noise isn't as good as other versions (like the -60258 you have).
