In this example, the current timestamp is:
Current TimeStamp(6) -------------------------------- 2010-03-09 19:23:27.620000+00:00
The following statement converts the TIMESTAMP value '2010-03-09 08:30:00' to a TIME WITH TIME ZONE value, where the time zone displacement is based on the time zone string, 'America Pacific'.
SELECT CAST(TIMESTAMP '2010-03-09 08:30:00' AS TIME(0) WITH TIME ZONE AT 'America Pacific');
The result of the query is:
2010-03-09 08:30:00 ------------------- 00:30:00-08:00
