Answer 1

It looks like a unix timestamp:

Tue, 25 Mar 2014 20:46:17 GMT

In .NET:

var epoch = new DateTime(1970,1,1,0,0,0,0,System.DateTimeKind.Utc);
var dt = epoch.AddMilliseconds(1395780377459);

Answer 2

I think the date is in milliseconds format. So you can try this:

DateTime date = new DateTime(long.Parse(1395780377459));
date.ToString("yyyy-MM-ddThh:mm:ssZ");

or simply

var time = TimeSpan.FromMilliseconds(1395780377459);

Also the if the date is in json format then you may try this as mentioned in this answer:

var date = new Date(parseInt(jsonDate.substr(6)));
