When you test an expression that uses a port with the Date/Time or Timestamp with Time Zone data type, you must enter sample data for the port using the required date format string.
To enter sample data for a port with the Date/Time data type, use the format MM/DD/YYYY HH24:MI:SS. When you evaluate the expression, the Expression Editor displays the result using the format that you specify in the expression. If you omit the format string in the expression, the Expression Editor displays the result using the same format MM/DD/YYYY HH24:MI:SS.
To enter sample data for a port with the Timestamp with Time Zone data type, use the format MM/DD/YYYY HH24:MI:SS TZR. When you evaluate the expression, the Expression Editor displays the result using the format YYYY-MM-DD HH24:MI:SS.NS TZR.
