You need to tell ntpdate which NTP server to query. Although
one certainly can run ntpdate periodically to synchronize the
time (and I think a default Ubuntu installation does this via
/etc/cron.daily), it's also common to run ntpd.
As NTP configuration of a Ubuntu system isn't related to Gerrit,
please consult another help forum.
