JSON Stringify changes time of date because of UTC

Question

My date objects in JavaScript are always represented by UTC +2 because of where I am located. Hence like this

Mon Sep 28 10:00:00 UTC+0200 2009 

Problem is doing a JSON.stringify converts the above date to

2009-09-28T08:00:00Z  (notice 2 hours missing i.e. 8 instead of 10) 

What I need is for the date and time to be honoured but it's not, hence it should be

2009-09-28T10:00:00Z  (this is how it should be) 

Basically I use this:

var jsonData = JSON.stringify(jsonObject); 

I tried passing a replacer parameter (second parameter on stringify) but the problem is that the value has already been processed.

I also tried using toString() and toUTCString() on the date object, but these don't give me what I want either..

Can anyone help me?

Answer 1

Recently I have run into the same issue. And it was resolved using the following code:

x = new Date(); let hoursDiff = x.getHours() - x.getTimezoneOffset() / 60; let minutesDiff = (x.getHours() - x.getTimezoneOffset()) % 60; x.setHours(hoursDiff); x.setMinutes(minutesDiff);

JSON uses the Date.prototype.toISOString function which does not represent local time -- it represents time in unmodified UTC -- if you look at your date output you can see you're at UTC+2 hours, which is why the JSON string changes by two hours, but if this allows the same time to be represented correctly across multiple time zones.
