I has installed datetime on haxe (haxelib install datetime) to get timezone offset. It run ok on Neko. But when I run on Android (haxelib test android), it runtime error. What's wrong?

Please help me.

import datetime.Timezone;

class DateHelper 

{

    public function getTimeZone():Void{

        trace(Timezone.local().getOffset(Date.now()));

    }

}
