    Hi ksmith0411 ,

    Whether you need to save the first row as variable which named 'Hour_Part' and create the calculated column like this:

    Column 2 =
VAR Hour_Part =
    TIME ( HOUR ( Actual[Start Time] ), MINUTE ( Actual[Start Time] ), SECOND ( Actual[Start Time] ) )
RETURN
    SWITCH (
        TRUE (),
        Hour_Part > TIME ( 8, 0, 0 )
            && Hour_Part < TIME ( 9, 0, 0 ), TIME ( 9, 0, 0 )
    )

        Hi ksmith0411 ,

        Noticed that there are duplicated rows in the table so that the table visual and matirx visual would just show the aggreated value.

         

        Basically you can create the below query in Power Query editor:

        let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMrC0MjBQcPRV0lEyNLAyNAUxY3WiQRxjmLgRiBkAFYeydZSMQRqhosYgnWBRUyS1pBgdCwA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Start Time" = _t, #"End Time" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Start Time", type time}, {"End Time", type time}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Time", each List.Times(#time(8,0,0),13,#duration(0,1,0,0))),
    #"Expanded Time" = Table.ExpandListColumn(#"Added Custom", "Time"),
    #"Changed Type1" = Table.TransformColumnTypes(#"Expanded Time",{{"Time", type time}}),
    #"Added Custom1" = Table.AddColumn(#"Changed Type1", "Diff", each if [Time] >= #time(Time.Hour([Start Time]),0,0) and [Time] < [End Time]  then if [Time] > [Start Time] and [Time] = #time(Time.Hour([End Time]),0,0) then Duration.Minutes([End Time]- [Time]) else if [Time] < [Start Time] and [Time] = #time(Time.Hour([Start Time]),0,0) then Duration.Minutes(#time(Time.Hour([Start Time])+1,0,0) - [Start Time]) else 60 else 0),
    #"Changed Type2" = Table.TransformColumnTypes(#"Added Custom1",{{"Diff", Int64.Type}})
in
    #"Changed Type2"

    Try it this way--assume your prior step is named PriorStep:

     

    = Table.AddColumn(PriorStep, "Next Hour", each Time.StartOfHour(Time.From([End Time] + #duration(0,1,0,0))))

    I agree that I would probably do this in the query editor, but here is a DAX column expression that should work.

     

    NewColumn =
    IF (
        AND (
            Actual[Start Time] >= TIME ( 8, 0, 0 ),
            Actual[Start Time] <= TIME ( 9, 0, 0 )
        ),
        TIME ( 9, 0, 0 ),
        BLANK ()
    )
