Excel/VBA converts dates to American format on transpose/paste from VBA

Question

I\'m working in a British context right now. Which I think I have set up in regional settings (Windows 7 in a corporate context, Excel 2016, ver 1803 (I think this may also

If you do not specify a cell format, it appears to be replaced with a date format for that country format. It is likely that you want to format the cell appropriately.

According to my tests, it seems to automatically recognize when I set the date value, specify the cell format as UK or US, and then put the value back into the variable.

Our region has a default date format of yyyy-mm-dd.

test code

Sub test()
    Dim p_dtTermArray() As Date
    Dim vR() As Long
    Dim lgnumterms As Integer
    lgnumterms = 2

    ReDim p_dtTermArray(1 To lgnumterms)
    p_dtTermArray(1) = DateSerial(2018, 10, 1)
    p_dtTermArray(2) = DateSerial(2018, 11, 1)
    ReDim vR(1 To lgnumterms)

    vR(1) = DateSerial(2018, 10, 1)
    vR(2) = DateSerial(2018, 11, 1)
    With Range("a1").Resize(1, 2)
        .Value = p_dtTermArray
        .NumberFormatLocal = "dd-mm-yyyy"
    End With

    With Range("a2").Resize(1, 2)
        .Value = vR
        .NumberFormatLocal = "mm-dd-yyyy"
    End With

    Dim vDB, vDB2
        vDB = Range("a1").Resize(1, 2)
        vDB2 = Range("a2").Resize(1, 2)

End Sub

I found that when I transpose an array of date format, it changes to a character format. A way to prevent this would be to convert the matrix into code.

Sub test()
    Dim p_dtTermArray() As Date
    Dim vR() As Long
    Dim lgnumterms As Integer
    Dim r As Long, c As Long, i As Long, c As Long
    lgnumterms = 2

    ReDim p_dtTermArray(1 To lgnumterms)
    p_dtTermArray(1) = DateSerial(2018, 10, 1)
    p_dtTermArray(2) = DateSerial(2018, 11, 1)
    ReDim vR(1 To lgnumterms)

    vR(1) = DateSerial(2018, 10, 1)
    vR(2) = DateSerial(2018, 11, 1)
    With Range("a1").Resize(1, 2)
        .Value = p_dtTermArray
        .NumberFormatLocal = "dd-mm-yyyy"
    End With

    With Range("a2").Resize(1, 2)
        .Value = vR
        .NumberFormatLocal = "mm-dd-yyyy"
    End With

    Dim vDB, vDB2, vD() As Long, vD2() As Long

        vDB = Range("a1").Resize(1, 2).Value
        vDB2 = Range("a2").Resize(1, 2).Value


    r = UBound(vDB, 1)
    c = UBound(vDB, 2)

    ReDim vD(1 To c, 1 To r)
    ReDim vD2(1 To c, 1 To r)
    For i = 1 To r
        For j = 1 To c
            vD(j, i) = vDB(i, j)
            vD2(j, i) = vDB2(i, j)
        Next j
    Next i
    Range("d1").Resize(2) = vD
    Range("f1").Resize(2) = vD2


End Sub
