Time column

Hi, Student59 

Based on your description, I have created some measures to achieve the effect you are looking for. Following picture shows the effect of the display.

DAX:

New Column:

DateDown =

VAR _dateDown =

    CALCULATE (

        MAX ( 'Date'[Date] ),

        FILTER ( 'Date', 'Date'[Date] < EARLIER ( 'Date'[Date] ) )

    )

RETURN

    _dateDown

Measure:

TimeDiff =

VAR _date1 =

    SELECTEDVALUE ( 'Date'[Date] )

VAR _date2 =

    SELECTEDVALUE ( 'Date'[DateDown] )

VAR _diff_second =

    DATEDIFF ( _date2, _date1, SECOND )

VAR Hours =

    INT ( _diff_second / 3600 )

VAR Minutes =

    INT ( MOD ( _diff_second, 3600 ) / 60 )

VAR Seconds =

    MOD ( _diff_second, 60 )

RETURN

    IF (

        NOT ISBLANK ( _date2 ),

        FORMAT ( Hours, "00" ) & ":"

            & FORMAT ( Minutes, "00" ) & ":"

            & FORMAT ( Seconds, "00" )

    )
