dual booting / time problem

cuk · 01-17-2008, 08:05 AM

Hello,
I have this strange problem:
I am dualbooting with slackware and ubuntu studio. Whenever I boot into ubuntu, the next time I boot slackware the time shifts exactly one hour. So if it is 4 o'clock it shows 3. I usually fix it through kde, but it is a bit annoying. Any ideas? Thanks in advance.

You don't say whether it's shifting forwads or backwards...and you don't say whether you have automatic summertime correction on either of the systems. I would be inclined first to go into both systems and make sure they both have the same "base" time (that is, not the "summertime-corrected" time) and both either have summertime correction on or off. Then check the time (hardware and software) at boot and shutdown on each OS. with that information, you should get some hints

Wow, that was quick! It went backwards. But the solution was much simpler. I checked the box where it sets the time automatically from the public time server and all is fine. Where was I looking before posting? Thanks again.

Hi,

Can I ask about your booting process between Slackware and Ubuntu? I have just set the same thing up and was keen to see another perspective.

IMHO, slackware is using the local time of the CMOS on the mainboard. But Ubuntu may have changed the time of the CMOS, and displays a local time according to your time zone. The following method is from the internet, which I haven't tested:

Edit the file in Ubuntu:
/etc/default/rcS

Look for this line:
UTC=yes

Change it to:
UTC=no

Hope it helps.

Thank you, syg00. :-) And I'd like to help if you want to learn Chinese.
