B4J Question [BANano] [SOLVED] Incorrect DateDiff Calculations

Log(DateDiff("2020-02-28", "2020-03-31"))  'returns 32   need dateutils lib
Sub DateDiff(CurrentDate As String, OtherDate As String) As Int
    DateTime.DateFormat = "yyyy-MM-dd"  
    Dim CurrDate As Long
    Dim OthDate As Long
    CurrDate = DateTime.DateParse(CurrentDate)
    OthDate = DateTime.DateParse(OtherDate)
    Dim p As Period = DateUtils.PeriodBetweenInDays(CurrDate, OthDate)
    Return p.days
End Sub

#if javascript
    function datediff(currentDate,otherDate){
        var dateS = moment(currentDate);
        var dateE = moment(otherDate);
        var duration = moment.duration(dateS.diff(dateE));
        var days = duration.asDays();
        return days
    }
#End If

Sub DateDiff(currentDate As String, otherDate As String) As Int
    Dim res As Int = BANAno.RunJavascriptMethod("datediff", Array(currentDate, otherDate))
    Return res

Log(DateDiff("2020-03-31","2020-02-28")) ' should return 32
