Question How to replace ntpdate

Hi there,

Hi have a group of computers + a server (all debians) connected to each other on a LAN.
For some reasons that I've not decided and that I can't change, the computers cannot connect to the net. Moreover, the server has no ntp service.
Though, I need to find a way of setting all computers clocks synchronised. I don't need a great precision but less than 10 seconds would be fair.
Is it totally insane to just launch the following command every week in a cron? Is there a better solution?
Code:
date -s "$(ssh someuser@server "date '+%Y-%m-%d %H:%M:%S'")"

Thanks for your help.
Santiago

Can't you make one of the computers an NTP server?

If every node in the LAN can see the server, start ntpd or xntpd as a time server, then start xntpd or whatever on each member of the LAN.

A time server does not necessarily have to connect to an outside time authority.

Thanks System Shock,
I can't make one of the computers an ntp server because they are often powered off.

Thanks jim mcnamara,
I'm not alowed to start ntpd on the server. That's why I was thinking of another way.


So according to you, it is totally unthinkable to use my technique to have all computers roughly at the same time.
