Moment.js set the base time from the server

Question

I have been reading the documentation, and cannot seem to find a method to set the date from the server as opposed to the client?

For example something like this

Answer 1

The best way to do this would be to ask the server once for the current time and then compute the offset between the server time and the client time. A function can then return the server time at any stage by using the current client date and applying the server difference.

Here's an example:

var serverDate;
var serverOffset;
$.get('server/date/url', function(data){
   // server returns a json object with a date property.
   serverDate = data.date;
   serverOffset = moment(serverDate).diff(new Date());
});

function currentServerDate()
{
    return moment().add('milliseconds', serverOffset);
}
