+# In 20140914145549_migrate_to_new_members_model.rb we forgot to set the
+# created_at and updated_at times for new records in the 'members' table. This
+# became a problem after commit c8e78d972a5a628870eefca0f2ccea0199c55bda which
+# was added in GitLab 7.5. With this migration we ensure that all rows in
+# 'members' have at least some created_at and updated_at timestamp.
