    Hi JCKong 

    please try

    Duration =
    VAR CurrentTime = 'Table'[Punch Time]
    VAR CurrentNameDateTable =
    CALCULATETABLE (
    VALUES ( 'Table'[Punch Time] ),
    ALLEXCEPT ( 'Table', 'Table'[Name], 'Table'[Short Date] )
    )
    VAR TableAfter =
    FILTER ( CurrentNameDateTable, 'Table'[Punch Time] > CurrentTime )
    VAR NextTime =
    MINX ( TableAfter, 'Table'[Punch Time] )
    RETURN
    COALESCE ( NextTime, CurrentTime ) - CurrentTime

Hi tamerj1 ,

Encountered an issue when the time stamp passed the next day, example:

Shift Date: 11/10/2023 Punch Time 1:  11:00 PM
Shift Date: 11/11/2023 Punch Time 2: 12:30 AM

    Ctreate a Punch DateTime column by adding Date and Time then use the following 

    Duration =
    VAR CurrentTime = 'Table'[Punch Time]
    VAR CurrentNameTable =
    CALCULATETABLE (
    VALUES ( 'Table'[Punch Time] ),
    ALLEXCEPT ( 'Table', 'Table'[Name] )
    )
    VAR TableAfter =
    FILTER ( CurrentNameTable, 'Table'[Punch DateTime] > CurrentTime )
    VAR NextTime =
    MINX ( TableAfter, 'Table'[Punch DateTime] )
    RETURN
    IF (
    'Table'[Activity] = "Logout",
    0,
    COALESCE ( NextTime, CurrentTime ) - CurrentTime
    )
