    Time resets to UTC at boot in Knoppix 6.2.1

    I've noticed that time always resets to UTC at boot in spite of local settings. I think I found a couple of problems in /etc/init.d /knoppix-autoconfig. I've fixed them as described below, but please let me know if there is a regular fix for it.

    1. In start_clock function I've changed <checkbootparam utc || UTC="-u"> to <checkbootparam utc && UTC="-u">. Looks like an obvious bug to me, but let me know if I've missed anything.

    2. I've moved a call to start_clock function after udev completed created devices, because in the original version hwclock was called before /dev/rtc was created and it caused an error message "file /dev/misc/rtc doesn't exist". To see the error you'll need to change /dev/null to a real file.

    Please let me know when a fix is available.

    Wow it's quite surprising that it takes so long to hear about this problem for the first time. Perhaps it's my ignorance. I wonder how other people have dealt with this problem. For me I have overriden the original thing, I do 'hwclock --localtime -s". I used to have problem get the correct time after I booted into Windows. After doing this, my clock is still correct after I boot into Windows and back to Knoppix.

    I am guilty of ignoring this problem. I think it just didn't take precedence over getting Knoppix up working the way I wanted. Now it is no longer an issue. Fixed somewhere in the upgrades I guess.

    It can't be. No way this problem can be fixed by a debian packages updates. It has to be some scripts have been modified.

    I noticed after posting: when booted into openbox, my conky script reports UTC even as the lxd taskbar clock reports PDT.

    The conky clock script needed to be offset from system time rather than GMT offset it used on the computer it came from. That means my system time is set at UTC (GMT) at boot and LXDE panel clock is offset correctly from system time, maybe from a configuration on install.

    Glad to see a discussion on this.

    My knoppix 6.2.1 reads out in local time ok here.

    However, in my other life, I can watch Ubuntu 10.04.1
    start with local time and see it reset itself to GMT.

    I can remember getting crosswise with dual boots to windows,
    but I think I'll try some ideas mentioned here to see
    if I can't get Ubuntu straightened out, after all.

    Thanks, all, for the ideas.

    PS

    In my Ubuntu 10.04.01 case, a new 2Gb SD card version,
    I noticed the system started in local time, but went to GMT
    when the wifi network clicked in.

    I'd never clicked the date/time display to set its parameters.
    You guessed it, default on the date/time applet was UTC, not localtime.
    I think this solved my problem, unless win7 complains.

    System Clock

    Using knoppix 6.2.1 based on the conversation I played around with hwclock command. "hwclock -r" set the clock to my system clock, remained successful after reboot.

    1)dpkg-reconfigure tzdata 2) date MMDDHHmmCCYY 3) hwclock --localtime. These three steps are another alternative. However when I did 4) hwclock --systohc - it changed my windows clock. When I corrected Windows - it put me back at square one in Knoppix (step 4 did me in - this time). I believe this problem centers around the fact that /etc/adjtime is never created. Maybe I will have to learn how to create based on "man hwclock".
