Javascript: Convert a UTC Date() object to the local timezone

I have a Date() object that contains a UTC date, which I need converted to the users local timezone. Does anybody know how I could do this? :-)

I found this for you: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/UTC

The way you use it is: var x = Date.UTC(yyyy, mangmo, dd, hh, mi, ss, ms); // now x is a timestamp in milliseconds (it's a number, not a Date object) var y = new Date(x); // now y is the Date object you said you wanted Arguments to Date.UTC are as follows:
yyyy is the year (for example, 1984 or 2016)
mangmo is the mangled month (a number from 0 to 11)
dd is the day of the month (this isn't mangled, it's the same as on a wristwatch or wall calendar)
hh is the hour of the day (0 to 23)
mi is minutes, ss is seconds, ms is milliseconds (I don't think I need to explain these)

This is an old thread, but just in case anyone else stumbles across this issue, here's how I got around this problem.

UTC dates from ASP.Net

In my example, I wanted my ASP.Net service to return dates in the user's local timezone, even though the date values were stored in SQL Server in the UTC timezone.

I'm pretty sure it is done for you automatically.

>>> d = new Date('Fri, 10 Jun 2011 19:49:23 UTC');
Sat Jun 11 2011 07:49:23 GMT+1200 (New Zealand Standard Time)
>>> d.getHours();
7

I usually create a new Date object and use the Date.setUTC* functions to copy the date information.
