I too used adjtimex to get the clock to behave much better, and run ntpd on top of that and it keeps things in check. A munin plot of my time statistics for an alix2d3 board is attached (assuming this list allows attachmennts!). The trick is to get your clock to behave within the parameters that ntpd accepts first.<br>

</div>It depends.<br>
<br>
I had same problem with voyage 0.6.1 (distribution kernel 2.6.26) on Alix 2D3<br>
board. Time skew was like one second less every 20 seconds.<br>
<br>
I solved it with adjtimex package, which quite fixed constant time skew and<br>
then run ntpd on top of that.<br>
<br>
Interesting is, that with (self configured/compiled) 2.6.27 kernel there is no<br>
such issue. Also some time ago, voyage 0.5.2 (with distribution kernel) did not<br>
have any such problem with ntpd on that board.<br>
<br>
So yes, ntp is working on Alix boards. And most of time without any other<br>
help ;)<br>
