I am attempting to set the time on my S1 Phillips Tivo. I can successfully set the time to anything I want using SETTIME, but when I try to make it permanent with SETTIME -rtc, it sets the time to 12/31/1969. If I set the time, then pull the plug and re-power, the new default is also 12/31/1969. Am I doing something wrong?? Does SETTIME -rtc not work anymore? Can anyone help?
