Calculating time duration between two times with the whole number and 24 hr formats

Hi Ali5457 ,
please check the following solution.
I am using the #time-function in there to construct the result:

let
    Source = Table.FromRows(
        Json.Document(
            Binary.Decompress(
                Binary.FromText("i45WsjA0U9JRsjQ1U4rViVYyNDa1BHINTUwMlGJjAQ==", BinaryEncoding.Base64),
                Compression.Deflate
            )
        ),
        let
            _t = ((type nullable text) meta [Serialized.Text = true])
        in
            type table [LogTime = _t, tmAtScene = _t]
    ),
    #"Changed Type" = Table.TransformColumnTypes(
        Source,
        {{"LogTime", Int64.Type}, {"tmAtScene", Int64.Type}}
    ),
    #"Added Custom" = Table.AddColumn(
        #"Changed Type",
        "DiffInTime",
        each #time(Number.IntegerDivide([tmAtScene], 100), Number.Mod([tmAtScene], 100), 0)
            - #time(Number.IntegerDivide([LogTime], 100), Number.Mod([LogTime], 100), 0)
    ),
    #"Changed Type1" = Table.TransformColumnTypes(#"Added Custom", {{"DiffInTime", type duration}}),
    #"Inserted Total Minutes" = Table.AddColumn(
        #"Changed Type1",
        "Total Minutes",
        each Duration.TotalMinutes([DiffInTime]),
        type number
    )
in
    #"Inserted Total Minutes"
