That's not reliable because of daylight savings time. You need to convert from AS dates to NSDates with something like (adjust date string to match your settings):

on makeNSDateFrom_(theASDate)
	set refDate to date "Friday, 1 January 1904 0:00:00" as date
	set theDiff to theASDate - refDate - 3.061152E+9 - (time to GMT) + (current application's NSTimeZone's localTimeZone()'s daylightSavingTimeOffset()) as real
	set newDate to current application's NSDate's dateWithTimeIntervalSinceReferenceDate_(theDiff)
	return newDate
end makeNSDateFrom_

You're behind the times. Cocoa time begins in 2001.
