Date Variables available?

Fantastic solution, many thanks Brian.

Posting a further query here in case anybody has already figured this out. :)

I wish to display my date format as 01/Jan/2018.

I have figured out the "Jan" bit (using https://stackoverflow.com/questions/27480262/get-current-date-in-dd-mon-yyy-format-in-javascript-jquery)

but I am struggling a little to display the day as "01" and not just "1".

Solutions?

My current javascript command reads:

var m_names = new Array("Jan", "Feb", "Mar",
"Apr", "May", "Jun", "Jul", "Aug", "Sep",
"Oct", "Nov", "Dec");

var currentTime = new Date();
var month = currentTime.getMonth() + 1;
var day = currentTime.getDate();

var year = currentTime.getFullYear();
var dateString=day + "/" + m_names[month] + "/" + year;
var player = GetPlayer();
player.SetVar("systemdate",dateString)
