Apparently Windows will drift 8 hours behind local time and Ubuntu 8 hours in front.
I've set again ubuntu to synchronize with Internet server and reboot Windows. Windows time is normal and only ubuntu time drifted to 8 hours in front.

It didn't actually drift. It is just how the time is intepreted that makes the difference. Windows assumes that your BIOS time is set to local time, e.g. it is 11:15 now. So when you boot your Windows, it will tell you that your time is 11:15am in KL, Singapore (+8) time zone. This is actually not a good way of setting the clock, but like all things Windows they do it anyway regardless whether it is right or wrong.
Ubuntu (or any other OS I know) inteprets the BIOS time in a different way. It assumes that the time set on your BIOS is UTC time. This makes sense if you are a travelling notebook user since the time is always correct wherever you go (UTC time is contant regarless of position). The only thing you change is your time zone to match the time zone you are currently in. The advantage is that all date and time for all applications are correctly recorded as UTC (e.g. e-mails, etc). So you can send/receive messages around the world and the date/time stamp is always correct.
So if you want Ubuntu to show the correct time now, set the BIOS to 03:15. Set your timezone to "Asia/Kuala Lumpur" (which is +8) and you will see the correct local time on Ubuntu. If you wish to see UTC then right click on your date/time display and set the Preferences to show UTC time.
If i'm not mistaken you can set Ubuntu to interpret BIOS time as local time. I remember seeing it during installation of Ubuntu. I can't be bothered to find out how to do it now.
On the other hand you can try to find out if Window can accept UTC time setting on the BIOS. This is make it much easier since both systems now can have the same time.

Very true! I have done away with Windows on my laptop. Just formatted my sda1 to reiserfs.
Reiserfs seems to be faster than ext3, but I noticed a slowdown during startup. Normal?
Are you on 7.10? If so, then it is a little more sluggish compared to previous versions. You can see some people complaining on the Ubuntu forums already. Too much emphasis on eye-candy and not enough on substance. I don't think the file system has much to do with it.
Anyway I hope they do a good job on 8.04 which is suppose to be an LTS.
