How to get utc date from timestamp using javascript?

Question

I have a variable containing timestamp ( in seconds generated with php ), I used following code to create date object using javascript

var newdate = new Date(arrivalDate);

then used following code to get formated date in utc

var tempdate = newdate.getUTCFullYear()+'-'+('0' + (newdate.getUTCMonth()+1)).slice(-2)+'-'+('0' + newdate.getUTCDate()).slice(-2);

It returns me a 1 day before date, not sure how to get utc date from a timestamp.

Answer 1

var newdate = new Date(arrivalDate); newdate.toUTCString();
