We have log file in which we have to capture the first line matching "TIMESTAMP_ISO8601" against build_StartTime filed and last line matching "TIMESTAMP_ISO8601" against build_EndTime filed. After this we have to calculate the difference and should store the difference against duration filed. We tried with date filter but that's not working out we tried other many options which didn't worked. Can you help us here
