    • Constructor Detail

      • PGTimestamp

        public PGTimestamp​(long time)
        Constructs a PGTimestamp without a time zone. The integral seconds are stored in the underlying date value; the fractional seconds are stored in the nanos field of the Timestamp object.
        Parameters:
        time - milliseconds since January 1, 1970, 00:00:00 GMT. A negative number is the number of milliseconds before January 1, 1970, 00:00:00 GMT.

      • PGTimestamp

        public PGTimestamp​(long time,
                   java.util.Calendar calendar)

        Constructs a PGTimestamp with the given time zone. The integral seconds are stored in the underlying date value; the fractional seconds are stored in the nanos field of the Timestamp object.

        The calendar object is optional. If absent, the driver will treat the timestamp as timestamp without time zone. When present, the driver will treat the timestamp as a timestamp with time zone using the TimeZone in the calendar object. Furthermore, this calendar will be used instead of the calendar object passed to PreparedStatement.setTimestamp(int, Timestamp, Calendar).

        Parameters:
        time - milliseconds since January 1, 1970, 00:00:00 GMT. A negative number is the number of milliseconds before January 1, 1970, 00:00:00 GMT.
        calendar - the calendar object containing the time zone or null.
