Problem synchronizing date and hour with RaspberryShake

I configured my raspberry shake in Stand-alone mode in order to work in a place where i didn´t have internet access and I set the date and the hour manually, but now that I want to get the hour synchronized automatically it doesn´t work, i tried turning off the stand alone mode and rebooting but it didn´t work, then i tried turning off the ntp with the following command:
sudo /etc/init.d/ntp stop but the terminal said: “Command not found”. If someone could help me would be really nice!

Hi, can you please post the logs from the front end?
