Can I set the local time zone in my browser through Javascript?

Question

I know that I can get the local timezone offset through the new Date (). getTimeZoneOffset (). But where did Javascript get this information? Is there a way I can set it so that all future Date objects have the offset that I want? I tried to find the DOM in Firebug but couldn't find anything.

What I'm trying to accomplish is to convert an era into a readable format, but it should be in US / Central, regardless of browser settings. Because I use US / Central, this is not a fixed difference from GMT. So instead of a bunch of super nasty conversion steps, why can't I just tell Javascript that I am in the US / Central?

The implementation of ECMAScript is expected to determine the local time zone setting.

Not.

Have you considered using the library ?

Moment-Timezone currently allows you to set the default time zone of the browser using moment.tz.setDefault() .

You will need to use moment() instead of Date() , but this is still a good update on top of the weird JS date object.

I understand this is an old post, but momentJS is a powerful javascript library for managing date and time objects
