I tested it in ash of busybox. I see it doesn't work in dash. So your 
suggestion is the best I know.

Hopefully final version :)

SYSTEMDATE=`date -u +%4Y%2m%2d`
read TIMESTAMP < /etc/timestamp
if [ ${TIMESTAMP#????????}${TIMESTAMP%????????} -gt $SYSTEMDATE ]; then
     date -u $TIMESTAMP
     /etc/init.d/hwclock.sh stop
fi
