Thank you both for the replies! Actually, the strings are not the problem. The "human" date/time to millisecond conversions are wrong.
12/25/2011 should equal 1324789200. My converted time (from the screen output) 12/25/2011 is -877432832. And when the drill-down is done it shows that Christmas is either in 1997 or 1942. Thoughts?
