I don't know which package this bug belongs to, so I am going to just describe how it acts hoping that will be categorized appropriately. Sorry for any inconvenience.
I am running Kubuntu Lucid beta 2 on a Lenovo IdeaPad S12 (Intel Atom N270, Intel GMA 950 Graphic Card).

> lsb_release -rd
Description:    Ubuntu lucid (development branch)
Release:        10.04
>

Expected behaviour: boot system, the clock should run normaly, with no
delay and not requiring a running network connection or special setup,
except setting up the time zone during installation.

Observed behaviour: boot system; if there is no network conection, the
system time runs about two times slower as the real time. If I plug in
the internet cable, the time is being corrected in about one second,
even though I didn't set it up to automatically update from the internet
in the control center. If I then plug out the network cable, time
continues to run normaly, with no delay even the whole day. Restarting
the system will beginn to delay the time if I don't establish a
connection to internet at least one time and at least a few seconds.

I also tried the currently stable version of Ubuntu (Karmic, Live CD)
and observed the same behaviour.

This issue cannot be a hardware problem due to the following facts:
1) booting XP doesn't cause any time delay
2) if I correct the system time and then turn off the computer for a few hours (the whole night) and then turn it on again, the time is correct at start up but immediately beginns to delay.

I don't now what other information should I provide but I am willing to
help as much as I can.
