|How can I calibrate the clock of clients ?|
|You have to install and turn on the ntp server. Take Ubuntu as an example,|
1. install ntp service in the server by "apt-get install ntp"
2. re-deploy clients by dcs -> others -> re-deploy
3. turn on the ntp server for client by "drbl-client-service ntp on"
Then everytime when client boot, the service will query the ntp server to calibrate time.
