*** Testcase
CREATE TABLE t1(a TIME)PARTITION BY HASH (EXTRACT(MICROSECOND FROM a));
SET @@global.table_open_cache=-1;
SET @@session.max_statement_time=TRUE;
INSERT INTO t1 VALUES(1),(1),(1),('1a'),(1),(0);
SELECT CONVERT_TZ(1,1,a)FROM t1;
May be we need to run the testcase twice to reproduce the bug.
