    Hi everybody!

     I have been reading a lot of old mails in this list
    about hour adjustment. But I see thay are based on
    adjusting hardware-clock and system-clock and my
    problem is diferent.
     I have a C program that receives the hour from a gps
    device (connected through a serial port) and tries to
    adjust the system-clock to that gps-hour. This is
    possible with a C function called "adjtime". So, the
    only thing I get using adjtime function is the
    system-clock is more and more far away each time.
    Adjtime DOESN'T adjust anything!!
     I have tested it using "settimeofday" instead of
    adjtime. Settimeofday changes the time more abruptly
    and there are more problems with files date. So, is
    not a good option.
     My distro is Suse 9.0. I have tested it in Suse 9.1
    and it doesn't work. But, I have tested the same
    program in RedHat 7.2 and 8.0 and adjtime works
    right!!.
     The only diference I have seen between Suse and
    RedHat machines is when I run the command "adjtimex
    --p". At Suse I got:
      TICK = 1000
      FREQUENCY = 0

    And RedHat:
      TICK = 10000
      FREQUENCY = 0

    I have tried to change the tick in Suse machines to
    10000 but it doesn't let me (it says: "invalid
    argument")
    I hope somebody has any idea. In any case, thanks a
    lot.

    Eva
