Ubuntu Date & Time update via NTP

Command Line ntpdate

Ubuntu comes with ntpdate as standard, and will run it once at boot time to set up your time according to Ubuntu's NTP server. However, a system's clock is likely to drift considerably between reboots if the time between reboots is long. In that case it makes sense to correct the time occasionally. The easiest way to do this is to get cron to run it every day. With your favorite editor, create (needs sudo) a file /etc/cron.daily/ntpdate containing:
Make sure that you make this new file executable:
sudo chmod 755 /etc/cron.daily/ntpdate
