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
