Oracle FROM_TZ Function
https://www.databasestar.com/oracle-timezone-functions/ The Oracle FROM_TZ function is used to convert a value in a TIMESTAMP data type, and a specific TIME ZONE, to a TIMESTAMP WITH TIME ZONE value. It’s a helpful conversion function if you work with times and time zones a lot. The syntax of the FROM_TZ function is: FROM_TZ ( timestamp_value, timezone_value ) The parameters of this function are: - timestamp_value: the value in a TIMESTAMP format to convert. - timezone_value: this is the timezone value that the timestamp_value will be converted in to. If you want to know what values can be used as a timezone value, you can look in the database view here: SELECT * FROM v$timezone_names; For more information about the Oracle FROM_TZ function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-timezone-functions/
