 Description   

In the "mysql" client, I run this query to force a warning:

SELECT TIME('10:10:10.11111111111');

Now I exit the session, start "mysql" again, and run this query:

SHOW WARNINGS;

It returns the warnings from the previous session:

+-------+------+--------------------------------------------------------+

| Note  | 1292 | Truncated incorrect time value: '10:10:10.11111111111' |

I'm raising the priority because it looks like a security issue to me – the previous warnings are shown even to a different user.
