The drift file is where ntpd stores a frequency correction snap shot.

The Undisciplined Local Clock is documented at
http://www.eecis.udel.edu/~mills/ntp/html/drivers/driver1.html (as well
as the driver1.html pages at doc.ntp.org). There are a number of
adjustable parameters which may be used to trim this "ref-clock".
