Super small and eazy to implement feature: Time span when zoomed in in the graph

After zooming in, the timeline under the graph shows the start and end date/time for the zoomed-in period.

I would suggest adding a new number showing the time span for this duration in DD:HH:MM:SS format (or as you see fit).
I’m currently using this stat a lot and have to calculate it every time. I want to know how long the PC was idle (it was on, and I was away), and how long I was using certain apps.

If this number will clutter the UI, can you add a setting to show/hide it?

Thanks.

@Hany.Alom thanks for your feedback on showing the time span for the duration shown. I will discuss with our team!
