I read the man page for ntpd and it looks like ntpd can either be a 
daemon that wakes itself up on interval and updates the time in your 
machine or actually broadcasts time to other machines. In the man page 
it notes that with the '-q' option it mimics the behavior of ntpdate, 
"which is to be retired".
I then poked around at /etc/ntp.conf and it looks like the default is to 
just listen. There was a line commented out about broadcast.
Am I correct in believing that the default for ntpd is to just update my 
time on a regular interval and not broadcast the time to the network?

To be or not to be, that is the question
                2b || !2b
(0b10)*(0b1100010) || !(0b10)*(0b1100010)
        0b11000100 || !0b11000100
        0b11000100 || 0b00111011
               0b11111111
        255, that is the answer.
