Here's the corrected memo.  And I compiled it.

The JDBC escape format for Timestamp and Date is '1999-12-31 23:59:59:999'

You can use the escape format within a SQL statement, e.g:  "INSERT INTO
TABLE_1 VALUES ('1999-12-31')";  But this may not be accepted exactly as
shown by all JDBC drivers.

The recommended way is to use a prepared statement and send it a Timestamp:

import java.sql.*;
import java.util.GregorianCalendar;

class Ttest {
public static void main(String[] args) {
     // For Java 2:  The Calendar classes take care of Timezone issues
     // and year entry is 0 based.
     // all Calendar values in raw form represent GMT.

         GregorianCalendar cal = new GregorianCalendar();
         cal.set(1999,11,31,59,59);              // Parameterized set()
allows y,m,d,h,m,s but not milli's.
         cal.set(cal.MILLISECOND,999);   // So a 2nd set() is required
formilli's.
         Timestamp tsvalue1 = new Timestamp(cal.getTime().getTime());
              // Note: 1st getTime() converts Calendar to Date.
              // 2nd getTime() converts Date to long.
              // Timestamp constructor requires a long.

     // For JDK 1.1.x (deprecated in JDK 1.2)
     // the parameterized constructor does not account for Timezones
     // and the year is 1900 based. (In both Timestamp and Calendar sets,
the month is 0 based).

               Timestamp tsvalue2 = new Timestamp(99,11,31,23,59,59,999);
                    // Causes deprecation note.
     try {
       Connection con = DriverManager.getConnection("url");

       PreparedStatement pstmt = con.prepareStatement("INSERT INTO TABLE_1
VALUES (?)");
       pstmt.setTimestamp(1,tsvalue1);
       pstmt.execute();
    } catch (Exception e) {}

 }
}
