Overview

OBSOLESCENCE WARNING!!!

The "Rate" processor is being obsoleted. Please do not use in any new agent development.

If you feel you need this processor, please check out the "Epoch Counter" processor and see if that will meet your needs. If not, then you can always do this calculation yourself within your agent.

This processor will be removed from the code base shortly...
