Class DateTimeValue

  • public class DateTimeValue
extends java.lang.Object
    This class represents a date or time value as it is represented in the database. In contrast to java.sql.Date, java.sql.Time and java.sql.Timestamp, which are based on java.util.Date, this class does not represent the time as an offset from midnight, January 1, 1970 GMT. Instead, it holds each component (year, month, day, hour, minute, second, nanosecond) as it would have been represented in a given calendar. Since it does not hold information about the time zone for the time it represents, it does not point to a well-defined point in time without being used together with a java.util.Calendar object.
