DISTINCT SQL Command

i trying to execute this line:

SELECT DISTINCT QID FROM "USERNAME"."ANSWER" WHERE Nickname =? ORDER BY Time DESC
OFFSET 0 ROWS FETCH NEXT 5 ROWS ONLY

And I get this error msg:

The ORDER BY clause may not contain column 'TIME', since the query specifies DISTINCT and that column does not appear in the query result.

What would be the problem?
