JS date object is not parsing correctly

Question

We currently save the date in this format: 12/12/2011 8:00:00 PM.

When I parse it in JS Date object, it converts into this: Tue, 13 Dec 2011 00:00:00 GMT.

I do not believe this is a timezone issue because we are -4 GMT and it does not add up. Any ideas?

var start = new Date("12/12/2011 8:00:00 PM");
alert("12/12/2011 8:00:00 PM");
alert(start.toUTCString());

Is the original date string meant to be in UTC/GMT as well? Cause, as is, Date assumes it to be a "local" date string. — Jonathan Lonowski

It seems to add up perfectly. "12/12/2011 8:00:00 PM" in GMT-4 is exactly "Tue, 13 Dec 2011 00:00:00 GMT".

EDIT Use toLocaleString to get the date and time in your local time zone.

start.toLocaleString()

I see... thanks for the answer. How do I convert it to my local GMT -4 if I need to use the getTime() functionality?

What is the output that you are looking for?

Actually it's correct, thanks, I forgot to take into account 12/24 hour display.
