So you shut it down at 20101003 and boot it at 20101006, that should
give you roughly:
SYSTEMDATE=`date "+%Y%m%d"` -> 20101006
TIMESTAMP=`cat /etc/timestamp | awk '{ print substr($0,9,4)
substr($0,1,4);}'` -> 20101003
NEEDUPDATE=`expr \( $TIMESTAMP \> $SYSTEMDATE \)` -> 0
So why is your rtc having a date older than the shutdown date?

Koen
