How to sum all dates of a repeatingGroup

[viniciusmoura]

Hello,
I have a repetitive Group that shows a list of dates, from these dates I want to sum the time.

EXAMPLE:
User Registered: Nov 20, 2022 1:00 am

Shortly afterwards he recorded: Nov 20, 2022 1:30 am

In this scenario I want the bubble to tell me:
The total time is: 2:30

In Bubble, I find the operations of max, min, mean, median, but I don’t find sum.
See image:

I think you can just subtract the two dates, and format it as minutes, right?

Something like this:

EDIT: Sorry, but I saw you want to ADD the times, but you should be able to do that as well.
