I strongly advice you and anyone caring about computer security to read 
up on NTP in the forms of Prof. Dave Mills book, as well as the many 
online resources. He spent good time on figuring out ways to suspect 
everyone and then find methods of handling this situation. You can do a 
lot with a standard NTP if you only care to read up on it.

Hehehe... hope I didn't scare you too much :)

Which is exactly what I was hoping for. I recommended this list as there 
is no better way to pick up on all the odd bits and pieces that involve 
the concept of "time" that we think we understand, but most doesn't.

Feel welcome! I have been waiting for you to de-lurk yourself and start 
participate. I hope your questions and comments triggers the interest of 
many, and we get a good debate.
