I was having this problem with a computer and I did the following to get it under control:
$> cat /etc/ntp.conf | grep burst
server ntp.ubuntu.com burst iburst
server pool.ntp.org burst iburst
That sends 8 packets instead of just 1 to the ntpserver.
The real fix for this problem was replacing the CMOS battery in the motherboard. After that, ntp just work.
