How to convert a timestamp string to local time using javascript?

Question

I have a JSP page in which I am pulling timestamp stored in database as string which has the form Thu Aug 21 2014 22:09:23 GMT+0530 (India Standard Time).

Of Course, I am able to display it as it is in the page, however I was looking for a solution in javascript that would enable me convert this timestamp as per user's local timezone.

Is there a way to do this ? Or for such a timestamp it's not possible ? Any help is greatly appreciated, well my question may sound silly as I am still familiarizing myself with javascript.

Thanks

Answer 1

You may try this

var timezone = new Date().getTimezoneOffset();

From MDN

The time-zone offset is the difference, in minutes, between UTC and local time. Note that this means that the offset is positive if the local timezone is behind UTC and negative if it is ahead. For example, if your time zone is UTC+10 (Australian Eastern Standard Time), -600 will be returned. Daylight savings time prevents this value from being a constant even for a given locale

EDIT:

var d = new Date(myYear, myMonth, myDate);
d.setTime( d.getTime() + d.getTimezoneOffset()*60*1000 );
