   It's also tied to duration.  The fix is https://github.com/westonpace/arrow/commit/ec9a5a433e27b56c85214bee77fe3b1be74c07dd although a proper PR should add tests as well as check the other checked functions (e.g. add_checked, etc.)
   
   It turns out that the "skip nulls" behavior is something that has to be specified per-kernel and it wasn't being specified for the duration kernels.  Is this something we need to fit into 12.0.0?  If so I can try and carve out some time later this week for a PR.
