cherry-pick #14405 to release-3.0

Signed-off-by: Lonng heng@lonng.org

What problem does this PR solve?

The parse string to date inconsistent with MySQL:

mysql> select convert('1201012736.0000', date);
+----------------------------------+
| convert('1201012736.0000', date) |
+----------------------------------+
| NULL                             |
+----------------------------------+
1 row in set, 1 warning (0.01 sec)

mysql> select convert('1201012136.0000', date);
+----------------------------------+
| convert('1201012136.0000', date) |
+----------------------------------+
| 2012-01-01                       |
+----------------------------------+
1 row in set, 1 warning (0.00 sec)

The MySQL will check the hms even if the target type is Date.

Will it break compatibility?
