Is there a way to get the timezone id instead of the timezone offset from the oracle?
When I execute `SELECT SYSTIMESTAMP AS TIMEZONE FROM DUAL;` the returned result is `13-JAN-21 10.19.52.936031000 AM +05:30`.

When I retrieve this from Java using the `rs.getObject( "TIMEZONE ", ZonedDateTime.class )`, the ZonedDateTime object has both the `offset` and `zoneID` set to `+05:30`.

But what I expect to see is, `SELECT SYSTIMESTAMP AS TIMEZONE FROM DUAL;` should return `04-JAN-21 02.40.50.000000000 PM ASIA/COLOMBO` And the Java ZonedDateTime for the query should have the `offset` set to `+05:30` and the `zoneID` set to `Asia/Colombo`.

Is there a way to set up this in DB level or Java level? Current `DBTIMEZONE` is set to `+05:30`.
