> The documentation for the date_trunc function includes a few sample SELECT statements
to show how the function works: [https://spark.apache.org/docs/2.3.0/api/sql/#date_trunc]
> In the sample SELECT statements, the inputs to the function are swapped:
> *The docs show:* SELECT date_trunc('2015-03-05T09:32:05.359', 'YEAR'); 
>  *The docs _should_ show:* SELECT date_trunc('YEAR', '2015-03-05T09:32:05.359');
