title: How can I access NTP clock in java
body: <p>I have a distributed program written in java. I want my nodes access a synchronized physical clock. </p>
  
  <p>I know NTP is a protocol for physical clock synchronization. I know that I can install it on linux by sudo apt-get ntp. </p>
  
  <p>My question is when I install it, how can I access this synchronized clock in my java program? I mean what happens when I install ntp on my machine? my <strong>system</strong> <strong>clock</strong> will be sync? </p>
  
  <p>Thanks :)</p>
