The clock applet drifts in time. Clock is set to "synchronize with internet ..." so it is correct at startup, but then if I stay inactive for some time, may be 5 min as well as 1 hour, the clock stops ticking. If I start to be active again, then the clock applet moves again, but the time is now late.
And it is not only the applet that is wrong, but the whole system date, because when I run
date in a terminal, the time is also wrong.
Clarification : Sorry, may be my question was not clear. Here is my bug report to ubuntu :
Expected Behaviour :
Clock-applet displays the correct time,
Observed Behaviour :
Displayed time is drifting
How to reproduce :
If I get away from my computer for some times, the time displayed by the clock applet drifts. But the date command also show the wrong time. Moreover, sleep interval also get wrong. To debug this, I tested the following script :
#!/bin/bash while [[ true ]] do date >> clocktest.log hwclock >> clocktest.log sleep 300 done
Must be run as root because of hwclock. Il launched it :
and got away from my computer
Here is the output log :

Line 1 and 2 show the first time through the loop.
Line 3 and 4 show the bug : while date (and sleep) thinks 5 minutes have elapsed, hwclock shows that 15 minutes have elapsed.
Line 5 to 12 shows normal behaviour, except now date is late by 10 minutes. Behaviour is normal because I was back at my desk using the computer.
Having clock applet displaying the wrong time is one thing, but having the whole system time wrong (since sleep gets confused too) is a major bug.
Hardware : It is a fujitsu siemens amilo xi 2550 notebook. It was working fine with ubuntu 8.04
