Hi, I have experienced some trouble with a Text field being populated with a Date/Time DataType input control. I am converting the passed in parameter (text date/time string) to a Timestamp in a sibling parameter with the following formula in the Default Value Expression. Code: new java.sql.Timestamp(((new SimpleDateFormat("EEE MMM dd HH:mm:«»ss zzz yyyy"«»)).parse($P{From})).getTime()) The Date/Time DataType InputControl fields/parameters (prompted for) are 'From' and 'To'. The fromTimestamp parameter is produced using this formula. The same thing occurs with the toTimestamp parameter. These fromTimestamp and toTimestamp parameters are not prompted for. When I log the queries, the log shows that the date/time is correct most of the time. Once in a while the time changes to be -6 hours (the time zone offset for here). I just reproduced the problem. Here's from the log: First try: 09:04:34,201 DEBUG JRJdbcQueryExecuter,http-8080-Processor24:206 - Parameter #1 (toTimestamp of type java.sql.Timestamp): 2008-01-07 00:00:00.0 09:04:34,203 DEBUG JRJdbcQueryExecuter,http-8080-Processor24:206 - Parameter #2 (fromTimestamp of type java.sql.Timestamp): 2007-12-31 00:00:00.0 Second try: 09:04:50,118 DEBUG JRJdbcQueryExecuter,http-8080-Processor25:206 - Parameter #1 (toTimestamp of type java.sql.Timestamp): 2008-01-06 18:00:00.0 09:04:50,119 DEBUG JRJdbcQueryExecuter,http-8080-Processor25:206 - Parameter #2 (fromTimestamp of type java.sql.Timestamp): 2007-12-30 18:00:00.0 I didn't change my input parameters (passed into 'From' and 'To'). This was done using the JasperServer interface (v2.1.0). I did nothing more than press the 'Report Options' button, and re-submit the same info. 12 successive submissions following this did not reproduce the problem. Then on the next submission, there it was again. Is there a bug? Am I don't something wrong? Thanks much, -Steve
