We have migrated obi 12c to OAC
In obi 12c the timestamp format is DD/MM/YYYY and the timezone is Kuala Lumpur (GMT+8).
In OAC we have changed the time format settings for 'default user preferred time zone' and 'default time zone for date calculations' to (GMT+8) Kuala Lumpur, Singapore.
However, the report's date format is not showing as expected. After changing Locale to 'English-USA' in system settings and in My account locale to 'Default-English-United Kingdom' date format is working like DD/MM/YYYY
but how we can do this globally for all users?
