copy datetime value from csv into excel using macro

I'm trying to open a list of csv file and copy the data into different spreadsheets of a excel file. My script is as follows

Sub importcsv()
    Dim strFile As String
    Dim strCSV As String
    strFile = "D:\15049"
    strCSV = "A4260512_ECRec.csv"
    Workbooks.Open Filename:=strFile & "\" & strCSV
    Range("A1").CurrentRegion.Copy Destination:=Workbooks("test 150302.xlsm").Sheets("test2").Range("A1")
    Workbooks(strCSV).Close
End Sub

The problem I have is in my csv file there is one colume of date time data (dd/mm/yyyy hh:mm), when copying those to excel, some are copied in the right order, some are not. For example, 31/3/1990 is copied exactly but 1/4/1990 is copied as 4/1/1990. In my region setting, date format is set as d/mm/yyyy.

Anyone has any idea? Please help.

Thanks,
