Wrong date/ time in QtMoko v31 and v32

[Daniel MT]

Hey there.
Every time I restart the system the date/ time is reseted to the epoch
(using v31 and v32 installed on the sd card). While booting I get
several suspicious messages like
RTC_RD_Time: invalid argument
or
pcf50633-rtc pcf50633-rtc.0: hctosys: unable to read the hardware clock

I attached the output of dmesg at http://pastebin.com/GUKUrCu6

Any hint?, please.
