How to find difference between events for a transaction?

[marisstella]

Hello Everyone,
I want to find duration between the events in a transaction.
Let's say I have 100 events In a transaction, there is a failure at 49 th event and it is continued to 69th event so I want to calculate the difference between these two and find out how much time taken between these 20 events.
Can anyone of you help me on this?
