It only seems because it is what it prints. But in fact, you should not write logic this way. This is equivalent to:
insert into errortable (dateupdated, table1id) values (sysdate, 1083);
It seems silly to convert a system date to a string to convert it back to a date.
If you want to see the full date, you can do:
select TO_CHAR(dateupdated, 'YYYY-MM-DD HH24:MI:SS'), table1id from errortable;
