Changes to the Time zone from the System settings for the user interface (UI) reverts back with a new session
Jakarta, Kingston and London
- If the user makes the change to the "user profile", the next time he logs in, that is the time zone that will show up in the Time zone selector.
- But, if the user sees the time zone selector, and changes it to something different from his system or profile setting, it is ONLY for that particular browser session.
To have the time zone permanently updated for a user, the user will have to modify the time zone using the sys_user record and not from the System settings for the user interface (UI)
