Javascript Date() initialization in bad format

Question

I'm writing javascript multiplayer game, my server code is in nodejs. I need to synchronize time between server and client.

At server side i call Date() and send the date string to client. Client recieves:

Tue Apr 28 2015 15:37:01 GMT+0000 (UTC)

After initialization with:

var time = Date("Tue Apr 28 2015 15:37:01 GMT+0000 (UTC)");

the time variable set to local time is:

Tue Apr 28 2015 17:37:03 GMT+0200 (CEST).

If i run my server localy then time is importing correctly. Is problem in different time format, CEST vs UTC ?

Thank you for answers

Answer 1

There are various ways to handle the timezones in JS.

Set UTC time across system

use .setUTCHours() Here you can see how to use it.

Create a new UTC Date

new Date(Date.UTC(year, month, day, hour, minute, second))

Date.UTC is explained here

Correct the difference in timezones manually

var d = new Date(xiYear, xiMonth, xiDate);
d.setTime( d.getTime() + d.getTimezoneOffset()*60*1000 );

Answer 2

You can send from server date in milliseconds format and then converting milliseconds to the date in required format.

Server:

var time = new Date().getTime();

Cleint:

var date = new Date(time);
