Time Server

[Mark Schonewille]

Hi Andre,

Thanks for the advice. I'll consider it for the next version. I'm  
going to change it anyway, because I want to hook directly into the  
network time protocol and avoid using telnet.

Currently, I am only retrieving the time. I'm slowly getting familiar  
with the protocol and will probably apply the necessary math at some  
point.
