Returns

A TIMESTAMP.

In Databricks SQL, if any of the arguments is out of bounds, the result is NULL. In Databricks Runtime, if any of the arguments are out of bounds, the function returns an error unless spark.sql.ansi.enabled is false, in which case the function returns NULL. If sec is 60 it is interpreted as 0 and a minute is added to the result.
