DAX Time calculation between two timestamp

[MYDATASTORY]

Hi,

Kindly advice with actual Dax formulae to calculate the time difference.

If you're able to provide a sample of DAX based on below dammy data will be great.

The data will be presented in tabular form and also in visualization where Total Duration (HH: MM) will be grouped by ID and Month. Much appreciated in advance.

ID	Start Time	End Time	Expected Result in HH: MM
A	01:30:00	02:00:30	00:30:00 HH: MM
B	11:00:00	03:30:00	04:30:00 HH:MM

Expected Answer A on the table

Total Time: For A=00:30:00HH:MM

Total Time: For B=04:30:00HH:MM
Expected Answer B on the table

Total Time for all IDs =(Total Time: For A=00:30:00HH:MM)+(Total Time: For B=04:30:00HH:MM)=05:00HH:MM

So that works, but then the time won't sum in a table or matrix. How to fix this?  Please and thank you.

@Caroline_1900,

Try this measure. It's based on a measure in the link below.

https://community.powerbi.com/t5/Community-Blog/Aggregating-Duration-Time/ba-p/22486 

Time Diff = 
// Given a number of seconds, returns a format of "hh:mm"
VAR vDuration =
    SUMX ( TimeTracker, DATEDIFF ( TimeTracker[Start_Time], TimeTracker[End_Time], SECOND ) )
// There are 3,600 seconds in an hour
VAR vHours =
    INT ( vDuration / 3600 )
// There are 60 seconds in a minute
VAR vMinutes =
    INT ( MOD ( vDuration - ( vHours * 3600 ), 3600 ) / 60 )
// These intermediate variables ensure that we have leading zeros concatenated onto single digits
// Hours with leading zeros
VAR vHoursFormatted =
    IF ( LEN ( vHours ) = 1, "0" & vHours, "" & vHours )
// Minutes with leading zeros
VAR vMinutesFormatted =
    IF ( LEN ( vMinutes ) = 1, "0" & vMinutes, "" & vMinutes )
// Now return hours and minutes with leading zeros in the proper format "hh:mm"
VAR vResult =
    vHoursFormatted & ":" & vMinutesFormatted
RETURN
    IF ( vResult = ":", BLANK(), vResult )

Thank you v v much.  It works.  It works well.  It works really well!  IT WORKS!!! 🤣

Please accept my apologies for the delay in responding.  PowerApps design is not my full-time work. But this project is something that I have to make work for me to continue.

@MYDATASTORY, try this measure:

Time Diff = 
SUMX ( TestData, TestData[End Time] - TestData[Start Time] )
