Hi,
     I just bought TS-7800 with the Debian release 3.1 on a 512MB SD
card. After booting up, the RTC always gives a wrong time:"Sun Oct 25
15:12:14 1925". I tried to reset the system time and HW clock as
typical procedure through a 'CuteCom' terminal:
     -Setting the system time with 'date 103110302007'. It Works!
     -Setting the HW clock with 'hwclock --systohc', 
      then using 'hwclock --show' to check its status. However, the
system response a message:
"The Hardware Clock registers contain values that are either invalid
(e.g. 50th day of month) or beyond the range we can handle (e.g. Year
2095)."
     I have tried several times with different hwclock's options
already, but got the same result. I dumped the /driver/rtc below,
which looks missing a lot info, such as periodic-IRQ, -freq, etc. Is
there any clue here to fix the hwclock problem on TS-7800? Please let
me if you have any suggestion. Thanks.

Zheng
