ORA-01873: the leading precision of the interval is too small

SELECT * FROM USER_JOBS
ORA-01873: the leading precision of the interval is too small

SELECT * FROM DBA_SCHEDULER_JOBS
ORA-01882: timezone region not found

After a removal of the suspected job, and recreating it again the issue was fixed.

"suspected job" - there was a lock in database, and the job session was terminated with ALTER SYSTEM KILL SESSION command.

BEGIN

 DBMS_JOB.remove(23);
 commit;
END;
/
SELECT * FROM USER_JOBS

Now is working!
