Instead of using a CDR, I would like to be able to calculate the average value of an event frame attribute over the time span of an event frame. I was hoping to use the new AF analysis capability. How can I obtain the start and end time of the event frame in the expression portion of an analysis in AF? After obtaining the start and end times of the event frame, I would like to be able to valid the times for time span and then add 5 seconds to the start time and subtract 5 seconds from the end time. Using the new start and end time, I want to calculate the average over that time span.
