In MySQL, the query to retrieve the global spent time list is sometimes extremely slow (taking several minutes in some environments) due to an inefficient join order chosen by the query optimizer. This patch adds an optimizer hint to improve the join order and ensure consistent performance. Patch by Go MAEDA (user:maeda). git-svn-id: https://svn.redmine.org/redmine/trunk@23609 e93f8b46-1217-0410-a6f0-8f06a7374b81
