I would think that generation _time_ would be rather irrelevant (Unless 
your generation time is a million years :) ).  I would think that the 
fact that mice have a less efficient DNA damage repair system than humans 
do, for instance, and so THIS would lead to a higher "clock rate" for 
them vs us, that is, sequence variations will occur at a higher rate per 
replication.  Correcting for more rapid generation time, the mutation 
rate should itself be more important.  

The clock rate for HIV, taking mutation rate into account, should then be 
extremely fast.
