Geoffrey, you may or may not find this to be helpful but I've found it much easier to deal with times as longs than as instances of various date classes (java.util.Date, java.sql.Date, java.util.Calendar, etc). The timelong can be easily retrieved with date.getTime() or calendar.getTime().getTime(), and longs fit nicely on the AS side as well. When displaying time values in datagrids, for instance, I needed the timelong instead of the Date object in order to preserve the default sort behavior regardless of what type of string formatting was applied to the date.
