SQLTimestamp is stored in 3 ints - an encoded date, an encoded time and nanoseconds encodedDate = 0 indicates a null WSCTimestamp SQLTimestamp is similar to SQLTimestamp, but it does conserves space by not keeping a GregorianCalendar object PERFORMANCE OPTIMIZATION: We only instantiate the value field when required due to the overhead of the Date methods. Thus, use isNull() instead of "value == null" and getTimestamp() instead of using value directly.
