A couple of things you may want to do:

a) Add to /etc/ntp.conf:
   server 127.127.1.1
   fudge  127.127.1.1 stratum 10

My cfengine configuration configures this all thus:

files:
   { /etc/ntp.conf
        AppendIfNoSuchLine "peer dantzig"
        AppendIfNoSuchLine "peer salesman"
        AppendIfNoSuchLine "server 127.127.1.1"
        AppendIfNoSuchLine "fudge  127.127.1.1 stratum 10"
        AppendIfNoSuchLine "peer firewall"
   }
   firewall::
   { /etc/ntp.conf
        AppendIfNoSuchLine "server ntlug.org"
	AppendIfNoSuchLine "server ntp0.cornell.edu"
	AppendIfNoSuchLine "server eagle.tamu.edu"
	AppendIfNoSuchLine "server black.hex.net"
   }

b) You may want to take the system clock and push to CMOS
   clock once in a while (especially when you shut down!) using
   hwclock.  The latter is the crucial bit; it appears that it has been
   renamed from "clock" to "hwclock."

	hwclock --systohc

   is the likely command you want.
