With this code, you can sinchronize the controller time with a NTP server.
You can turn any computer to a NTP Server with a lot of Free softwares (Dimension4 for Ex,), that sinchronize the PC time with a Web NTP Server. The computer just have to answer telnet command on the port 13.
You can configure a list of the servers that you want to sinchronize, the time to poll the server, the number of retry before to go to the next server, etc…
The default parameters are in the initial value on the strategy.
