Wow, this new type of clock is not even 100 times more longterm stable
than the Cs fountain clock, it's even short-term stable as a H-maser,
obviously.
In the NIST article: http://www.nist.gov/pml/div688/clock-082213.cfm
it's told, that the 1s instability is the same as the 400,000 sec or 5
days stability of the Cs fountain clock, ie. 1e-15..1e-16, I assume.
Perhaps NIST can provide the Allan deviation already.
