What is the URL of the timer server used by Ubuntu?

The settings page just shows the radio option "Automatically from Internet", but it does not show the actual server URL, like in WIndows.

enter image description here


Usually, ntp.ubuntu.com. This is supported by example preseed files and the value used by the server and network installation methods (for which, the debug output shows ntp.ubuntu.com as the value for the NTP server). To check the server status and time, you can run ntpdate in debug mode (to see if there are other problems), or in query mode (to just see the time):

ntpdate -d ntp.ubuntu.com # Debug mode
ntpdate -q ntp.ubuntu.com # Query mode

  • Is there a way to actually see the time on the server other than looking at my OS clock. The address does not return anything in a browser so i am guessing the browser cannot understand the NTP protocol. – faizal Jul 17 '14 at 10:54

    @faizal The time on the server? You can run the ntpdate command in debug mode: ntpdate -d ntp.ubuntu.com. Or in query mode: ntpdate -q ntp.ubuntu.com. – muru Jul 17 '14 at 10:57

Your system will use Ubuntu's NTP server at ntp.ubuntu.com by default.

To find what NTP server is being used, run:

grep ^server /etc/ntp.conf

If you get an error, then NTP is not installed. To install it, just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:

sudo apt-get install ntp

    thanks. i got it at /etc/default/ntpdate – faizal Jul 17 '14 at 11:02

ntpdate is deprecated. You can use this command to get the status and see which server is being used:

systemctl status systemd-timesyncd
