seeing some time related failure

error[E0282]: type annotations needed for `Box<_>`

also fixed the path borrow check issue

  1 pick 644ca1f fix borrow check error for `path`¬

Thanks a lot @chenrui333! Both you and @th1000s fixed this, and f441d4d is already in main. But thanks a lot for the fix.
