Make sure you have the IP addresses of your NTP servers in BOTH the
/etc/ntp/ntpservers and /etc/ntp/step-tickers files.  The first thing
the startup script does is try to run "ntpdate" using the entries in
the ntpservers file.  That will drag your clock into sync with the
servers by brute force, then ntpd can keep it synced.
