The following specification ensures that a Daylight Saving Time value is returned: If you do not add the TZD format element, and the datetime value is ambiguous, then Oracle Database returns an error if you have the ERROR_ON_OVERLAP_TIME session parameter set to TRUE. TIME_ZONE can be set to the following values: Default local time zone when the session was started (local), Absolute offset from UTC (for example, '+10:00'), Time zone region name (for example, 'Asia/Hong_Kong'). The performance penalty arises because the TIMESTAMP WITH TIME ZONE (TSTZ) data is transferred using a local timestamp instead of UTC.
