Review comment:
I have been looking for a website to put as a reference in the error
message and I'm having a hard time finding a specific site that talks about
"Spark not supporting timestamp without timezone" fields. Could I maybe please
get some pointers as to where I should look. I saw some relevant information on
this site :
https://docs.databricks.com/spark/latest/dataframes-datasets/dates-timestamps.html
