Comments:
`total_seconds` is only used once.  If it can be replaced with a one-liner, go ahead and get rid of the function entirely.
It can't be a one-liner because we have to decref the object `PyObject_CallMethod` returns.  Even though it's only used once, I think the code reads better as a separate function because it splits out the python bookkeeping from the json logic.
lgtm. can you push again to force CI's to run again (just to make sure passing on windows).
