Date the DST problem persisted in a Date Javascript object

I have this simple javascript code

var d = new Date(2011, 9, 8);
alert(d); // Show: Fri Oct 7 23:00:00 UTC-0400 2011

Important: My time zone is Santiago de Chile , and I set my computer clock: October 2, 2011.

A warning shows that Day 7 !! ... why? How can i fix this? (The problem is this day only)
