I wonder if pool.ntp.org mentioned at the article is active. If so I'd prefer that one (the dialog allows you to add more time servers - adds them to the bottom of the list and selects them, but you can then deselect them if you just want to enrich that list for future use). I suppose pool.ntp.org is a broker server, not the real time server itself, it just picks another time server and sends you there. Btw, it seems to default to ntp.ubuntu.com now.

Could even talk to Microsoft's time server, it's a standard protocol isn't it after all? Also user may want to manually sync once (at this PC I'm writing now the RTC battery is dead, have no spare one at hand and it starts up with wrong time), but they aren't shown that option anymore by default and can't spot it at Add/Remove apps by searching say for Time. Searching for NTP give results for NNTP (newsgroups) apps. Wonder why there's no small app/applet to sync the time once (instead of calling a payphone to get the latest time or searching the net to find some webpage with current time for your zone) What would it cost them to use NIST’s time server (for more free ones checkout the drop-down list at synchronize time pane of recent Windows).

How to set NTP time sync from terminal:

sudo aptitude install ntp ntpdate

Be sure to access the application from System / Administration / Time and Date
and select a server closest to your location.

Under system settings > Internet & Networks > Connections > Proxy > Use the following login information section is disabled. Whenever I use a browser it prompts me for a user name and password. But when synching the system clock with a time server it gives an error saying unable to connect to time server. Is there a way around this to manually set the username and password somewhere?

My laptop's onboard battery is dead so each time I start up I have to manually set the time. Would have been great if HappySpaceInvader had actually posted how to set it from the terminal.

In a vanilla installation, there are no options for NTP in the Date & Time settings, nor are there any prompts to install NTP support. It looks as if this feature has been discontinued unless you have the knowledge to set it up manually at the command line (fortunately, I do). I imagine, this is to prevent all new Ubuntu users from synchonrising to the same default time server and never changing it to sync to one that is nearer to home. This is one of those areas where 'paid for' operating systems win out in my opinion. Microsoft and Apple can afford to set up and maintain a bunch of their own time servers (time.windows.com, time.euro.apple.com, etc.) for their users.

The ntp daemon uses almost no resources. On my system right now, there is approximately 300K of RAM used by it, and no processor usage. Do a quick search for ntpd vs. ntpdate, and you'll find 'everyone' recommends ntpd. It keeps track of your synchronizations, and accounts for some other variables to keep your clock even more accurate than just running ntpdate at startup. Of course, if you really don't care about having an accurate clock all the time, by all means setup a cronjob or startup script with ntpdate, but that's my 2 cents.
