Are you sure both your Linux installations are set to the correct time zone?

The BIOS clock in some file/web servers may be set to Universal Time (UTC) even when the server isn't actually located in the Greenwich Time zone, and then each user's local time is derived accordingly. I know that Linux can operate in this way, as I've seen that configuration option during the installation of several distros.Bianca Desktop time remains constant and accurate local time (12h) regardless of BIOS time.
Based on your description of the glitch, I'd look at whether or not Bianca is handling your BIOS clock as though it's running UTC instead of your local time.
To check if this is your situation, go Terminal and enter the following command (you can copy-and-paste from here)...
Code: Select all
cat /etc/default/rcS | grep UTC
However, if the above command displays "UTC=yes" then Bianca is treating your BIOS clock (a.k.a the server clock) like it's running Universal Time, while you (the user) are configured for New York City time, so that's what appears on your taskbar. Bianca (Linux) will try to keep both times correct, synchronizing via Internet time-servers if possible (thus defeating your manual BIOS adjustments).
To tell Bianca that the BIOS time is your local time, you can edit a configuration file. Go into Terminal for superuser gedit...
Code: Select all
gksu gedit /etc/default/rcS
If needed, go Bianca > Administration > Time and Date to set the correct time and date that's currently showing on your taskbar.
Restart your PC. Adjust the BIOS clock to your local time... for the last time!
Did any of this apply to your time problem?

Re: shutdown/restart causes bios time to advance 4 hrs
How do you access BIOS information on all computers? I'm joining an organisation which deals with old computers & I am to use the BIOS on startup to find out what RAM etc it has. Is there one key which is applicable to all computers?

The correct key to access your computer's BIOS differs widely with different PC/motherboard manufacturers. It can be any of the F# keys (on my LG laptop, it's F2, on my HP PC, I do believe it's the ESC key), or the delete key, or a combination of the above (maybe even with CTRL and ALT thrown in). The only way to know for sure is to randomly press keys on your keyboard until you get into the BIOS, or look for manuals (either in print or online from the manufacturer's website) for the particular brand and model of the computer.

Great solution to a common problem for dual booting with Windows. Thanks for the information.
