Table 4-4 contains the names and descriptions of the datetime format parameters. You can find out the database time zone by entering the following query: You can set the default session time zone with the ORA_SDTZ environment variable. You can have access to a much greater number of time zones by combining the FROM_TZ function and the datetime expression. Specify the TIMESTAMP data type as follows: fractional_seconds_precision is optional and specifies the number of digits in the fractional part of the SECOND datetime field. Then both "Oct-28-2007 01:30 PDT" and "Oct-28-2007 01:30 PST" are valid timestamps in version 2. Insert the date with the TO_DATE function.

The performance penalty arises because the TIMESTAMP WITH TIME ZONE (TSTZ) data is transferred using a local timestamp instead of UTC.
