Quantum mechanics itself does not have a natural time scale at which "interesting things" start to happen, but some theories built using quantum mechanics do.  It helps if you think of quantum mechanics as being like Newton's laws:  it is not a theory itself so much as a metatheory that provides ground rules for how to construct theories of nature.

(And yes, I actually am a quantum physicist. :-) )
