Dear List! I'd like to set up the system to update the RTC based on the system clock (set by an external source) automatically. I found that with the do_adjtimex function this can be done. I have to clear the STA_UNSYNC bit in the .status filed of the timex structure. It seems that the .maxerror field also has to be set to 0 also, because if I don't set it to 0 the STA_UNSYNC bit will be set by the system automatically. Can anyone help me how this should be implemented? TIA && Good byte! -- Kernelnewbies: Help each other learn about the Linux kernel.
