It's slightly more complicated than this. The system has a time zone. Each user has their own time zone which defaults to the system time zone. The user launching the JVM chooses the time zone for the JVM. So the default progression looks like this: 1. Explicitly set at JVM launch using -Duser.timezone 2. Explicitly set by user using TZ environment variable 3.

The JDBC driver is responsible. And I still think that Connector/J is doing the right thing. When you connect via Connector/J, the driver grabs the time zone from the server and figures how (and if) to convert time values between the two. > I guess the real error was not initially leaving the MySQL RDS in > GMT.

You can also change the db time zone in the db config if you want it different from the system (which you do not want IMHO). - -chris -----BEGIN PGP SIGNATURE----- Comment: Using GnuPG with Thunderbird - https://www.enigmail.net/ iQIzBAEBCAAdFiEEMmKgYcQvxMe7tcJcHPApP6U8pFgFAl4WW1EACgkQHPApP6U8 pFgvcRAAiPPdACvG+kUv0paR9XGIZ4NsIl8y6ujxx+vvCqzjyzJ7QmsWifDLDeWq DALbvpK1JR6tlXcaQPGRV18yI8SkfDUBi/2gCpy7pjgYqXCO/h772QQ+qWqpiC8o S402a5GctvdXqD2Kd2xX2wK3oiHGqlQrzCvabt/Fgt4AQOIQJjX46evYu46X1mjZ BZ7utdZBeApK+iKDv0N/1yFS1NAEIqms06hnsYHcEqYAHkxTr1yyQkdFAUmVI3nV uPRagXEN/+IAOsOqULK69axK6ioesMZErGOWRbMFi/3WOkHaaI0eaor2OUQhoSK/ X7L8hy24mMWrXOV+LBmtw5tRj0K7eAeW30+dZFcYcWR4Hb50whvDlfnyqIT1/SSk Z3HtrqYT4QIsorU5/uifN2yDjVfuIqu8YDS5/BW8BWsa0hGaDbqR2JdszeR0t4Nf judacTtPVZThbqfoWsmvRNu0+chQITaZUpEtlSllNzlxmBcwYhsdPO8F7AWzh5i/ gxlbI6KMTO9BCm/0x4QprrROBNr9Zjnas6vXGVuijQDL3wcjQuVdfJKJlQ9OT3pw abi0Z/f5y66mCpN1qenvY328c9XbkQk+0NK1EkdyNLVCmKT1qFvYPU9XRjNmpXRB OvDnakziRvyDU/BMLLX7bGhr/YO3WGu1YvObRyFIFLy8gWjnHVs= =N+gY -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
