The reference implementation of ntpd is supposed to create/write a drift 
file at intervals of one hour.  Be certain that the account you use to 
run ntp has the necessary rights to create a file and/or that the 
directory you specified as the location for the file has permissions set 
to allow writing such a file.  It works for me, has for years now!
