I have a log that that has multiple utc times listed. The logs are ingested into Splunk and I have created a field extraction to show those times in my Splunk table query. Now I am trying to populate the ProcessingTime with the difference between two of the fields. I'm missing something. Can't get the ProcessingTime to populate. Any help would be great.
