How to change the timezone of Oracle SQL Developer / Oracle Data Modeler?

This worked for me

AddVMOption -Duser.timezone=GMT+5

If you need to change the time zone of Oracle SQL Developer (or Oracle Data Modeler), then this is how to do it:

  1. Go to the installation directory of Oracle SQL Developer.
  2. Open the file located at: sqldeveloper/bin/sqldeveloper.conf.
  3. At the end of file, add the following line: AddVMOption -Duser.timezone=GMT-4.

You will need to change the value GMT-4 to one that match one of the timezones in V$TIMEZONE_NAMES.

And that’s it!
