I am on Ubuntu 12.04 LTS, in the dialog "Time and Date settings" there is a set of radio buttons labeled as "Set the time", the two options are "Manually" and "Automatically from the Internet":
My current selection is "Automatically from the Internet" and I am fine with that apart from the fact that I would like to change the synchronization server (I would like to set it to ntp1.inrim.it). Is it possible without installing the ntp
package? I did not find any way to change the server from the dialog.
