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'
