Excel 2013: Displaying times in Milliseconds

I am trying to a) create a time with millisecond accuracy and b) display that in Excel.

What I have found using the below code is that Excel will show the correct milliseconds in the worksheet using the NumberFormat  "DD/MM/YYYY HH:MM:SS.000" but it will not show milliseconds in the debug window using the 'Format' command and instead rounds it up to the nearest second.

Can anyone else confirm this to be a known issue or have they got experience of this ?

Sub testMilliseconds()

    Dim dblMillisecond As Double
    Dim dblResult As Double
    
    dblMillisecond = 1.15740740740741E-08
    
    dblResult = dblMillisecond * 1750
    
    Debug.Print Format(dblResult, "DD/MM/YYYY HH:MM:SS.000")
    
    With Range("A1")
        .Value = dblResult
        .NumberFormat = "DD/MM/YYYY HH:MM:SS.000"
    End With

End Sub
