Actionscript 3 - 解析yyyy-mm-dd hh:mm:ss到Date对象的最快方法？

var dateString:String = "2022-01-01 12:00:00";
var dateArray:Array = dateString.split(" ");
var dateParts:Array = dateArray[0].split("-");
var timeParts:Array = dateArray[1].split(":");

var year:int = int(dateParts[0]);
var month:int = int(dateParts[1]) - 1; // 月份是从0开始的，所以需要减1
var day:int = int(dateParts[2]);
var hour:int = int(timeParts[0]);
var minute:int = int(timeParts[1]);
var second:int = int(timeParts[2]);

var date:Date = new Date(year, month, day, hour, minute, second);
