actionscript 3 - january 31 2012 UTC time jump -

i'm working on flash project uses xml-data database through php generate graphs. draw on right spot want convert dates numbers , thought date.utc(yyyy,mm,dd) answer. reason doesn't convert linearly. as3-code:

private function valuedispatcher(e:event):void {         debugfield.appendtext("succes= "+e.target.data.succes);         if (e.target.data.succes) {             var myxml:xml = new xml(e.target.data.xml);             var mylist:xmllist = new xmllist(myxml.children());             debugfield.appendtext("\nxml[0]= " + mylist[0]);             debugfield.appendtext("\nxml[0].time= "+mylist[0].time);             (var i:int = 0; < mylist.length(); i++) {                 var splitter:array = string(mylist[i].time).split("-");                 var seconds:number = date.utc(int(splitter[0]),int(splitter[1]),int(splitter[2]),1,0,0,0);                 var ar:array = [mylist[i].time, seconds, mylist[i].verbruik, mylist[i].corr];                 debugfield.appendtext("\nar= "+ar);                 maxtot = math.max(maxtot,mylist[i].verbruik,mylist[i].corr);                 values.push(ar);                 if(mylist[i].corr!=null){                     comparenr++;                     cumul1 += mylist[i + 365].verbruik;                     cumul2 += mylist[i].corr;                 }                }         }         else { fakedata();             debugfield.appendtext("\n values= "+values);         } }  private function fakedata():void {         var date: date = new date(2012, 01, 28);         var first:boolean = true;         var corr;         (var i:int = 0; <= 500; i++) {             var datestring:string = "" + date.getfullyear() + "-" + date.getmonth() + "-" + date.getdate();             var utcseconds:number = date.utc(date.getfullyear(), date.getmonth(), date.getdate());             var gebr:number;             if (first) {                 gebr = math.round((2.3 + math.random() * 40) * 1000) / 1000;                 first = false;             }             else {                 gebr = math.round((math.max(4, math.min(47, values[i - 1][2] - 5 + math.random() * 10)))*1000)/1000;             }             corr = 10;             if (i > 134) corr = -1;             var ar:array = [datestring, utcseconds, gebr, corr];             values.push(ar);             maxtot = math.max(maxtot, gebr, corr);             if(corr!=-1){                 comparenr++;                 }             date.date++;         }         (var j:int = 0; j < comparenr; j++)          {             corr = values[j][2] * 0.6 + values[j + 365][2] * 0.4;             values[j][3] = corr;             cumul1 += values[j + 365][2];             cumul2 += values[j][3];         } } 

so function fakedata() called when i'm operating offline otherwise should use xml data.

the problem seem have in 'web-mode': date.utc(2012,1,31) = 1330646400000 > date.utc(2012,2,1) = 1330560000000 while equal date.utc(2012,2,2) = 1330646400000

while in off-line mode line date.date++ seems make go straight 2012|1|29 2012|2|2

what happening here???
