Yes, that's probably quite good.  I was looking for a term which 
distinguished between drift (which I would understand as a long-term 
reasonable uniform movement), and the random offset from the drift 
component.  I got a little stuck with drift, though, as one quite often 
refers to both short-tem drift (which might be over a second, minute or 
hours depending on context, perhaps caused by temperature), and long term 
drift (which might be a day, month or year),and perhaps was caused by 
crystal aging.

Hornet's nest of terms!
