I want to use the javascript's toISOString() function and ignore the timezone.
var someDate; // contains "Tue May 26 2015 14:00:00 GMT+0100 (Hora de Verão de GMT)"
dateIWant = someDate.toISOString(); // turns out "2015-05-26T13:00:00.000Z"
The date to convert is Tue May 26 2015 14:00:00 GMT+0100 (Hora de Verão de GMT) but the converted date is 2015-05-26T13:00:00.000Z.
So, I need the date in the yyyy-MM-ddTHH:mm:ss:msZ but as you can see above it applies the timezone and changes the hour from 14 to 13.
How to achieve this?
EDIT
I am working on a C# MVC project and I can send the date as it is and manipulate it in the C#. It is my current solution but I am looking for a client side one.

Reset to default 8Based on the polyfill for Date.prototype.toISOString found at MDN's Date.prototye.toISOString:
if (!Date.prototype.toLocalISOString) {
(function() {
function pad(number) {
if (number < 10) {
return '0' + number;
}
return number;
}
Date.prototype.toLocalISOString = function() {
return this.getFullYear() +
'-' + pad(this.getMonth() + 1) +
'-' + pad(this.getDate()) +
'T' + pad(this.getHours()) +
':' + pad(this.getMinutes()) +
':' + pad(this.getSeconds()) +
'.' + (this.getMilliseconds() / 1000).toFixed(3).slice(2, 5) +
'Z';
};
}());
}
So just use this toLocalISOString instead of toISOString.
Your Javascript statements are producing the expected results. Tue May 26 2015 14:00:00 GMT+0100 is the same time as 2015-05-26T13:00:00.000Z. Unless you care about a fraction of a second, GMT, UTC, and Z all mean the same thing: mean solar time at 0° longitude, and keeping the same time all year (no change in summer; Iceland observes this time all year). "GMT+0100" means a time zone that is one hour later than 0° longitude, such the United Kingdom in summer. So at a given moment the time in Iceland is 2015-05-26T13:00:00.000Z and also Tue May 26 2015 14:00:00 GMT+0100 in London. Could you clarify what result you want to see? Perhaps you would like "2015-05-26T14:00:00" which is the ISO 8601 notation for some unspecified local time, presumably the local time of the puter displaying the Javascript. Or maybe you want "2015-05-26T14:00:00+01:00", which is ISO 8601 notation for the local time zone one hour ahead of 0° longitude, such as London in summer or Paris in winter.
Building on souldreamer's example, making it fully working and providing the local time offset:

Date.prototype.toLocalISOString = function () {

if (this.getTimezoneOffset() < 0) { timestamp = timestamp + "+" }

timestamp = timestamp + pad(Math.abs(this.getTimezoneOffset() / 60).toFixed(0));
