I believe a windows7 addition to a multiboot system has buggered up the time displayed on two other debian installations on the same computer, a X86_64 and an AMD64 respectively. I'm running unstable on the two Debian installations but #dpkg-reconfigure tzdata can't fix the problem.

At the moment the local time is displayed as 15:59 when in fact it is 19:59 and UTC is displaying the correct local time. (19:59) when it should be 23:59

I'm sure this is related to something win7 did, because I only noticed it after the additional installation. I just don't know how to change things back like they were.

Thanks,

Do the BIOS clock show the right time, or is it also 4 hours behind? I had a similar issue once and the solution was to edit /etc/default/rcS, and set UTC to no (UTC=no).

Linux assumes the bios clock is in UTC, so it adds 4 hours to it to get it to your local time.
Windows on the other hand assumes that the bios clock is on local time, so it does nothing.

In order to make windows do the opposite there is a registry setting, which I cant remember at this time.

In order to make your debian installation do the opposite, simply change UTC=yes to UTC=no, inside /etc/default/rcS.

Plus, I think this is one of the last questions asked by the debian installer in expert mode when you first install debian. It does not ask you in "simple" mode, so that may be the reason you did not see such option.

OK, thanks for these replies. My /etc/default/rcS is in fact UTC=yes..I'll change it and I assume my problems are over.
