Hi,

Diff command will give you difference between two search results. Refer below link for example:

diff can be used to get the difference between the epoch time.
Please see the below example where i used this query for setting my alert

your base query | eval MyDate=strptime(date,"%d %b %Y %H:%M:%S") | fieldformat StartTime=strptime(MyDate, "%Y-%m-%d %H:%M:%S") | eval Diff=tostring((StartTime-EndTime),"duration")
