Flex 4 utc date time format problem

here are my functions they work fine when timeoffset is round nu开发者_JAVA技巧mber(1,2,3,4...),but when is 3.5(3:30), 4.5(4:30) it doesnt work. Can someone help me with this :

private function init_vars():void
            {
timeZoneOffset = FlexGlobals.topLevelApplication.parameters.clock_time_zone; // I load this with js
                timeZoneOffset = 5,50; // just for test
            }

            private function tick(event:TimerEvent):void 
            {                   
                var local: Date = new Date();

                var utc: Date = new Date(local.getTime() + (local.getTimezoneOffset() * 60000));

                var utcTime:Number=utc.getTime();




                var new_offset_date:Number = utcTime + ((3600000) * timeZoneOffset);
                var new_date:Date = new Date(new_offset_date);              
                currentTime = new Date(new_date);
                showTime(currentTime); // another function just to display time                                 
            } 


private function showTime(time:Date):void
            {
                seconds = time.getSeconds();
                minutes= time.getMinutes();
                hours= time.getHours();

                            //rotate
                this.secondsPointer.rotation = (seconds * 6) - 90;
                this.minutesPointer.rotation = (minutes * 6) - 90;              
                this.hoursPointer.rotation = (hours * 30) + (minutes * 0.5) - 90;
                this.secondsPointer.visible = true;
                this.minutesPointer.visible = true;
                this.hoursPointer.visible = true;                           
            }

I ran your code and it worked fine. I just traced currentTime because I didn't have your showTime function, is it possible that the bug is in that function?

I would recommend to try something like the following if you can:

date.setUTCHours(date.getUTCHours() + hoursDifference); //5
date.setUTCMinutes(date.getUTCMinutes + minutesDifference); //30

Modifying dates using the time in milliseconds, depending on how/where/when you actually use the application might create weird bugs in case of daylight savings. And you don't want to deal with a bug that might happen only twice a year in only certain countries of the world.
