How to create TypeScript date object:
- new Date()
- new Date(milliseconds)
- new Date(datestring)
- new Date(year,month,date[,hour,minute,second,millisecond ])
Example:
function dateTest(date:Date):void{
var hours=date.getHours();
var minutes=date.getMinutes();
var seconds=date.getSeconds();
console.log("Current Time: "+hours+":"+minutes+":"+seconds);
}
var date=new Date();
dateTest(date);
function dateTest(date:Date):void{
var hours=date.getHours();
var minutes=date.getMinutes();
var seconds=date.getSeconds();
console.log("Current Time: "+hours+":"+minutes+":"+seconds);
}
var date=new Date();
dateTest(date);
function dateTest(date:Date):void{
var hours=date.getHours();
var minutes=date.getMinutes();
var seconds=date.getSeconds();
console.log("Current Time: "+hours+":"+minutes+":"+seconds);
}
var date=new Date();
dateTest(date);
