Are you actually in the EST zone? If so then that would explain it. I don't think time-zones are interpreted properly, they are probably equivalent to GMT+XX00, they likely ignore daylight savings and whatever. "EST" is also ambiguous, you might be getting the wrong result because it's getting confused. This will also be interpreted differently for people in different countries, you should stick to GMT numbers to keep it reliable.

Try changing "EST" to "GMT-0400".
