How to parse OpenWeatherMap date?

Question

JavaScript

Working with the openweathermap api, I encountered such a problem: they store the date in this format: "1436022000". What is this format and how to parse it into javascript date?
new Date(1436022000) returns the following: Thu Jan 01 1970 05:00:00

Answer 1

Unix time
Number of seconds elapsed since January 1, 1970
Hence the output
var date = new Date(1436022000 * 1000);
