    Keeping up with the times

    .
    I notice some peculiar things about tz=localtime in my situation,
    where I keep my hardware clock set to local time, and I prefer to see
    this local time on any desktop I might be using. The Windows 7 desktop
    has no problem with this arrangement, of course. But on this same machine...

    My Knoppix 7.0.5 LiveUSB has tz=localtime on the APPEND line of syslinux.cfg;
    My Knoppix 7.2 LiveCD has tz=localtime on neither the DEFAULT line nor the APPEND line; and
    My Knoppix 7.2 LiveCD-size LiveUSB requires tz=localtime on the DEFAULT line.

    Hi, @utu.
    I am using K 7.2 right now.
    I've got the local date and time on the clock by adding tz=localtime in
    /mnt-system/boot/syslinux/syslinux.cfg in the line APPEND of the section knoppix:
    APPEND lang=en keyboard=es xkeyboard=es apm=power-off initrd=minirt.gz nomce libata.force=noncq hpsa.hpsa_allow_any=1 loglevel=1 tz=localtime

    Greeting, Porteno.

    I don't know why adding tz=localtime to the APPEND line wouldn't work for me
    as it did in 7.0.5. I use a CD-size LiveUSB if that makes any difference.

    It should be noted that, should I want to use the command 'date', It assumes
    the value it is reporting is in UTC unless its given more FORMAT information.

    I installed Knoppix 7.2 DVD on a flashdrive. I also had trouble with the time. I read through the information posted by others.
    I editted this file on my flash drive ... k:\boot\syslinux\syslinux.cfg

    In my original syslinux.cfg file , the following records appear at lines 17,18 and 19.

    LABEL knoppix
    KERNEL linux
    APPEND lang=en apm=power-off initrd=minirt.gz nomce libata.force=noncq hpsa.hpsa_allow_any=1 loglevel=1

    I added "tz=localtime" at the end of record 19 , which starts with APPEND.

    APPEND lang=en apm=power-off initrd=minirt.gz nomce libata.force=noncq hpsa.hpsa_allow_any=1 loglevel=1 tz=localtime

    then saved the file.

    I then restarted the computer , booting from the flashdrive .
    The correct time is now displayed .

    With "cat /proc/driver/rtc; date" you can see the time of the BIOS clock and in the last line the time of your panel clock. I allways recomend to use UTC time within the BIOS and "tz=..." in the kernel line with your local parameters - for me "tz=Europe/Berlin".
    Code:
    $ cat /proc/driver/rtc; date
    rtc_time    : 17:09:13
    rtc_date    : 2013-09-11
    alrm_time    : 00:00:00
    alrm_date    : 2013-09-12
    alarm_IRQ    : no
    alrm_pending    : no
    update IRQ enabled    : no
    periodic IRQ enabled    : no
    periodic IRQ frequency    : 1024
    max user IRQ frequency    : 64
    24hr        : yes
    periodic_IRQ    : no
    update_IRQ    : no
    HPET_emulated    : no
    BCD        : yes
    DST_enable    : no
    periodic_freq    : 1024
    batt_status    : okay
