Date Format for System Date

Thank you!!!  I am learning so much from everyone here and this is what I was able to gather from everyone here and resources elsewhere.

Javascript  - using a variable to call the current date and an expiration date 180 days later

Code 1 System Date

var currentTime = new Date()

var month = currentTime.getMonth() + 1

if(month<10);

{

 month='0' + month;

}

var day = currentTime.getDate()

var year = currentTime.getFullYear()

var dateString=month + "/" + day + "/" + year

var player = GetPlayer();

player.SetVar("SystemDate",dateString);

Code 2 Expire Date - 180 days later

var someDate = new Date();

var numberOfDaysToAdd = 180;

someDate.setDate(someDate.getDate() + numberOfDaysToAdd);

var dd = someDate.getDate();

var mm = someDate.getMonth() + 1;

var y = someDate.getFullYear();

var dateString = mm + "/" + dd + "/" + y;

var player = GetPlayer();

player.SetVar("ExpireDate",dateString);
