Chapter 9. Managing time synchronization

There are several ways you might currently be handling synchronizing time-of-day clocks on your control workstation and processor nodes. You might already be using Network Time Protocol (NTP) either locally or through the Internet, or you might be using some other time service software. It is also possible that you have not established a method for synchronizing the system clocks in your computing environment.

The SP system gives you several options for time-keeping:

• If you have an established NTP time server, you can use it to synchronize and manage time on the SP system.
• You can choose an NTP time server from the Internet.
• You can run NTP locally on the SP system to generate a consensus time.
• You can choose to not use NTP at all, relying on other methods at your site. If you choose to not use NTP, you must have another way to manage clock synchronization.
