SYSTIMESTAMP
returns the system date, including fractional seconds and time zone, of the system on which the database resides. The return type is TIMESTAMP
WITH
TIME
ZONE
.
The following example returns the system timestamp:
SELECT SYSTIMESTAMP FROM DUAL; SYSTIMESTAMP ------------------------------------------------------------------ 28-MAR-00 12.38.55.538741 PM -08:00
The following example shows how to explicitly specify fractional seconds:
SELECT TO_CHAR(SYSTIMESTAMP, 'SSSSS.FF') FROM DUAL; TO_CHAR(SYSTIME --------------- 55615.449255
The following example returns the current timestamp in a specified time zone:
SELECT SYSTIMESTAMP AT TIME ZONE 'UTC' FROM DUAL; SYSTIMESTAMPATTIMEZONE'UTC' --------------------------------------------------------------------------- 08-07-21 20:39:52,743557 UTC
The output format in this example depends on the NLS_TIMESTAMP_TZ_FORMAT
for the session.
