I noticed the n900 clock had drifted a few minutes off.
Odd, since it has access to accurate time over the internet, the phone network (other phones use this), and the GPS.
The GPS should be obscenely accurate, so why does it let the clock drift? I've ticked the box now to update automatically, but am wondering what it does. There was no instant change, so will see in the morning if it has caught up.
Ntpd does not seem to be installed or in the repository.

BIG WARNING SIGN (devs want this or kill me if I don't):

NEVER USE MAEMO TESTING UNLESS YOU KNOW WHAT RIDE YOU'RE IN FOR!


ntpd can be found in maemo testing

OK, so that confirms that NTP is not standard.
Then what does the "update automatically" checkbox do then?

It enables clock synchronization with the cellular network, if an activated SIM is in the N900.

Thanks, but I don't think my network (3AU) supports that. I just switched it over to roam on Telstra and the clock was corrected before it jumped back to '3'.

I don't suppose there is a way to use GPS for time? Nanosecond accuracy would be cool :-)

My clock is also drifting noticably. I'm quite surprised by this because the N800 clock doesn't drift at all (and no, I don't have ntpd running). Either the N800 OS2007 uses some kind of built-in time synch whenever it's online, or that device's hardware clock is simply extremely stable. The N900 clock is drifting way too much.

I got openntpd working!

This is what I did!
Make sure you have a working internet connection!
Install rootsh over application manager if you haven't yet.

Open XTerminal

type:

Code:
sudo gainroot

apt-get install openntpd
(wait until it's done installing)

Then type:

Code:
ntpd
after around 20 seconds, the time on the N900 should have updated!

You can check whether you suceeded using the
Code:
date
command!

Everytime you want to update the time on your phone, you need to type

Code:
sudo gainroot
ntpd

If this works for you, that's great. I'm not seeing any change when I run this version of ntpd. In addition, this is not the way it's intended to work.

I would really like to see a working implementation of ntpd or some other form of ntp on the N900. At present, if my N900 is set to update time automatically (from AT&T), it's consistently six seconds fast. Otherwise it's consistently four to ten seconds slow.

Crikey, you must have a really tight schedule
