Installation changes system clock -Ubuntu 9.04/9.10

[Hank]

(BIOS Clock) System Clock unsetting bug 3/30/2010

Installation resets the system clock. I installed Ubuntu 9.10 amd 64 from CD under wubi. In my case the clock was correctly set to 11:10am under Windows 7 and after the installation it showed 6:16am.

When I installed Ubuntu 9.10 i386 the clock was 10:31am before install and the time after install was 5:34am

When I installed Ubuntu 9.04 the time was 11:48pm before install and the time after install was 6:54pm.

Based on my observations the installation process changes the hour value while leaving the minutes and AM/PM value unchanged.

I would expect the installation to leave the system clock alone when there is no time server to synchronize with.

In my case I did not have a network connected and accordingly did not have a connection to a timeserver. After the system connects to the internet the clock sets itself automatically.

I have only tested this on Wubi installs of Ubuntu 9.04, Ubuntu 9.10 i386 and 9.10 amd 64.

System is:
Dell 1546 Inspiron
AMD Turion Processor

(Note: It may be helpful to note that this sounds similar to "Bug #497504 Live CD changes BIOS clock" and
"Bug #561030 System clock runs about two times slower if no connection to internet")

Hi Hank,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/ . If the issue remains, please run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 571059

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Hi Jeremy,

How do I know which one is the latest development release?  Are you referring to 10.04?

Regards,

Hank

hi Hank,
    I suppose since 10.04 is out now I can't call it a Dev release anymore, but I'd appreciate your testing it and the mainline kernel mentioned above if possible. Every bit of data we can gather helps us narrow the root cause a little more.

Thanks!

Hello Everybody! I got Dell Inspiron 1564 with ubuntu 10.04 and Acer Aspire 1640z with ubuntu 9 and on both systems nothing helps stopping the automatic system clock manipulation. I feel like Ubuntu has started acting like Microsoft:)

[Andy C. (ndc)]

AFAIK this is not a bug, this is just how Linux in general uses the system clock. Linux sets the clock to UTC, while Windows sets it to the local time. Try setting the time zone to UTC in Ubuntu.

[Hank (hljandrich)]

Maybe it is true that Ubuntu starts out by default in the UTC time zone but if that were the case I would expect the clock to show the same time until I manually change the time zone. Also, when I switch back to Windows 7 the clock has been changed there as well. Therefore, as far as I can tell this is not a time zone issue.

Hello All ! I had been facing same problem in Ubuntu 10 exactly as described above and even changing the system clock and the windows clock (in cases with dual boot mode winxp or win7 with Ubuntu)

After over a month of research I found out that The problem was not even worth the research :)

Try This: Open the 1- Clock menu from Panel in your top right hand corner,
2- Edit your Time Zone and City Country etc. to the relevant city and country of yours
3- When you are done you see there is Calendar and below that you See a Heading Locations having EDIT button in its front
4- Below that you see a Weather map kinda thing and there you see a Dot starts blinking or atleast you see a dot there marking your longitudinal and latitudinal location,

You gotta double click that dot to set the location you edited just now as your home or otherwise at the bottom of this Calendar / Clock Window you see an Analog Clock and a Home Button infront of it, which will take the shape of HOME ICON as you usually see in Mozilla Browser for HOME.

When you see that icon on the right and your city name on the left beside the analog clock it means you are done.

If this solves your problem as it did mine then I would say its not a Bug it was just that we could not understand the Complex way that Ubuntu Deals the time in and thus giving us a tough time :)

Please ignore any spelling mistakes as I am using these weather and geography words / terms after some 20 years when I used to be in 6th Grade of school:P
