ntpdate doesn´t work by booting

Hi!

I wrote a 1 line script to use ntpdate. wenn I start the script manually it works. I put it in /etc/init.d and made symbolic links in /etc/rc3.d/and /etc/rc5.d/. But it doesn´t work when I boot. I still have to run the script manually. Can´ t work ntpdate during booting?

It won't work unless the network is already up.

Here's my solution:
I don't want the time checking more often than once a day (I do not want to annoy those timeservers!)

I put this line in root's crontab

Code:

5 * * * * /usr/sbin/chktime

So the script chktime is called at five minutes past every hour.

This is the script, it is very simple:

Code:

#!/bin/bash
# chktime 
# No need to check the time more than once a day, no matter how often
# this script is called
# Note the date format: we do NOT want spaces in the date!
NOW=`date +%a%b%d`
LAST=`cat /etc/.lasttimecheck`
if [ "$NOW" != "$LAST" ]; then
	echo -n $NOW > /etc/.lasttimecheck
	/usr/sbin/ntpdate uk.pool.ntp.org ; echo "ntpdate set the date" >> /var/log/messages
fi
