I use ntpd and have also used ntpdate, I think they are better than
manually setting the time (but you need internet connection).

From the S3C2440 datasheet, paragraph 17 (Real Time Clock), the year is
represented by one BCD byte. Values range from 00 to 99. May be linux
assumes that the minimum year is 2000 ?
You may want to try setting a date after 01/01/2000.
