NetFlow includes timestamp information that increases the level of detail TrafficInsights can provide. To maintain data accuracy, it's important these timestamps are correct. Once the clock in your equipment is right, it's the job of the Network Time Protocol (NTP) to keep the clock set correctly.
Refer to http://www.pool.ntp.org/ for more information about NTP.
