[lcottercertinia]

✨ Feature Request

It would be great to be able to toggle between elapsed time since the start of the transaction in ms and the the user's time (e.g. 10:58:42.869)

If I click on the number markers on the timeline it would be nice if it could toggle between elapsed time and user time.

🧩 Problem This Solves

Provides extra context, sometimes I want to know when something started and finished not just how long

🧠 Proposed Solution

Toggle between elapsed and real user time by either cliking on the time markers or via a toggle above flamechart. or both.
