TIME_ZONE = ‘[+ | -] hh:mm’
TIME_ZONE = LOCAL
TIME_ZONE = DBTIMEZONE
TIME_ZONE = ‘time_zone_region’
SELECT FROM_TZ(TIMESTAMP ‘2000-03-28 08:00:00’, ‘-9:00’) FROM DUAL;
select day from dual;
select SESSIONTIMEZONE from dual;
ALTER SESSION SET TIME_ZONE = ‘-7:0’;
ALTER SESSION SET TIME_ZONE = ‘os’;
ALTER SESSION SET TIME_ZONE = local;
ALTER SESSION SET TIME_ZONE =’-8:20′;
ALTER SESSION SET TIME_ZONE = DBTIMEZONE;
ALTER SESSION SET TIME_ZONE = ‘Australia’;
ALTER SESSION SET TIME_ZONE = ‘Africa’;
ALTER SESSION SET TIME_ZONE = ‘America/New_York’;
select TZNAME from V$TIMEZONE_NAMES where TZNAME like ‘Australia’;
select TZNAME from V$TIMEZONE_NAMES where TZNAME like ‘America%’;
SELECT DBTIMEZONE FROM DUAL;
