Question

I have this code:

function getTime(zone, success) {
        var url = 'http://json-time.appspot.com/time.json?tz=' + zone,
            ud = 'json' + (+new Date());
        window[ud]= function(o){
            success && success(new Date(o.datetime));

        };
    }

Which is part of code I had in the app before, it is not functional.

What it is supposed to do it connect to that server and get current time using JSON. I want it to just return the datetime or even better – the current EPOCH time. I am not sure how to modify it to make it work – should I just create a new date var and return it? Like,

var newDate = new Date(o.datetime)
return newDate?

The time on the website is in this object:

{
  "tz": "EST", 
  "hour": 19, 
  "datetime": "Sun, 04 Mar 2012 19:20:37 -0500", 
  "second": 37, 
  "error": false, 
  "minute": 20
}

Answer 1

If o.datetime is a valid date that the Date constructor can take and parse, you should be able to call the function with a callback and apply any method you like:

getTime(zone, function(result) {
    console.log(result.getTime()); // the timestamp, if result is a valid Date object.
});
