I have found under Linux that I can change the time using the date command, but when I reboot the machine the time is wrong again. It appears that for some reason Linux isn't actually changing the system clock. I'm not really sure what's going on with it. This problem doesn't occur with Windows NT. I can set the system clock just fine with NT and after a reboot the time will still be correct.
What am I doing wrong (other than occassionally using NT)?
