Invalid Attribute value Exception while adding Timestamp Attribute value

Question

Good Day friends,
I'm using IBM Directory Server 4.1 LDAP to maintain the Online User Registeration for a Web Application. I need to store the Timestamp at the time user registers, so that another java application of mine can delete non-active users within specific amount of time. But when i provide a value for "createTimestamp" attribute in LDAP using Java sql class object Timestamp, it gives me a exception of InvalidAttributeValueException. I tried inserting the entry with String, but without success. What is the type or format for createTimestamp Attribute? How i can bind a time or date object to this object? Any Help or Suggestions will be highly appreciated. Thanks in Advance. Cheers..!!
The source code is as follows:
public void createUserProfile(String afname, String alname, String aemail, String apassword) {
          String fname, lname, email, password;
          fname = afname;
          lname = alname;
          email = aemail;
          password = apassword;
          Date regDate = new Date();
          //java.sql.Time tsObj = new java.sql.Time(regDate.getTime());
          Timestamp tsObj = new Timestamp(regDate.getTime());
          String strTS = tsObj.toString();
          System.out.println("Created Date: "+tsObj);
          try {
               InitialDirContext ctx = new InitialDirContext(prop);
               BasicAttribute objClasses = new BasicAttribute("objectclass");
               objClasses.add("inetOrgPerson");
               BasicAttributes attrs = new BasicAttributes();
               attrs.put(objClasses);
               attrs.put("givenName", fname);
               attrs.put("sn", lname);
               attrs.put("mail", email);
               attrs.put("userPassword", password);
               attrs.put("createTimestamp", tsObj);
               ctx.createSubcontext("cn="+fname+",ou=Dept,o=InterComp", attrs);
               ctx.close();
               } catch (Exception e) {
               System.out.println("Error : " + e.getMessage());
               e.printStackTrace();
The Error is as follows:
Error : Malformed 'createTimestamp' attribute value
javax.naming.directory.InvalidAttributeValueException: Malformed 'createTimestamp' attribute value; remaining name 'cn=arun15382,ou=Dept,o=InterComp'

I've the same problem with lastModifiedTime:
java.sql.Timestamp cal = new java.sql.Timestamp(System.currentTimeMillis());
myAttrs.put(new BasicAttribute("lastModifiedTime", cal));
this results in:
javax.naming.directory.InvalidAttributeValueException: Malformed 'lastModifiedTime' attribute value; remaining name 'uid=tester,ou=people,dc=...'

Have you fixed it?
