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

NAME
nwfstime - Display / Set a NetWare server's date and time SYNOPSIS
nwfstime [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ] [ -s ] DESCRIPTION
nwfstime displays a NetWare server's date and time. You can also set a NetWare server's date and time from the local time. OPTIONS
-h With -h nwfstime prints a little help text. -S server is the name of the server you want to use. -U user user is the user name to use for login. To set the server's time, you need supervisor privileges. -P password password is the password to use for login. If neither -n nor -P are given, and the user has no open connection to the server, nwfstime prompts for a password. -n -n should be given if no password is required for the login. As you need supervisor privileges for setting the date and time, this option is probably not used very often. -C By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off this conversion by -C. -s With -s, nwfstime sets the file server's date and time according to the local date and time. nwfstime 12/10/1996 NWFSTIME(1)
