extends Datum

TIMESTAMP Class

The TIMESTAMP class provides conversions between the Oracle Date (ldx_t) data type and Java classes java.sql.Date, java.sql.Time, java.sql.Timestamp
The internal data for this object is stored as a eleven byte array in the super class' storage area. The bytes are arranged as follows:
```
      Byte       Represents
       0         Century (119 for 1990)
       1         Decade  (190 for 1990)
       2         Month
       3         Day      
       4         Hour
       5         Minute
       6         Seconds
       7         Nanoseconds
       8         Nanoseconds
       9         Nanoseconds
       10        Nanoseconds
  
```
Static methods are used for conversions.
