OK, now I see that my previous messages were unclear. You should try it like this: hwclock --directisa --show hwclock --directisa --set --date="23 Apr 2007 13:06:46" Adding HWCLOCKPARS="--directisa" to /etc/default/rcS means that this option is used when hwclock is called during boot-up and shutdown, but it has no influence if you run the command directly. Here is a rough outline of how things are supposed to happen: 1) The hardware clock keeps track of time while your computer is off. 2) Linux reads the hardware clock during boot to set the system clock and then Linux keeps track of time without reading the hardware clock again. Optionally you can use ntp or chrony to synchronize your system clock to a network time server. 3) Linux saves the system clock's current time to the hardware clock during shutdown. 4) See 1) If the hwclock command does not work then your computer sets the system clock to a wrong time during boot, and even if you correct the system clock later this will not be saved to the hardware clock when you shut down your computer. In summary: If you find an option to make hwclock work properly then you have to put that into /etc/default/rcS. You also have to set the system clock once more to the correct time (e.g. with the "date" command). From then on the time should remain correct across reboots. -- Regards, | http://users.icfo.es/Florian.Kulzer Florian | -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
