Be careful with time synchronization. It's one of most common problem in distributed environments. I guess your scenario is like below:<br><br><div class="gmail_extra"> - Controller Node (Synchronizing from external NTP servers and at the same time it acts as NTP server to compute nodes)</div><div class="gmail_extra"> - Compute Nodes (Synchronizing from controller node)<br><br>
