> {color:#e01e5a}inferTimestamp{color} option is missing in the list of options
> in {color:#e01e5a}DataFrameReader.json{color} method in the API docs missing

> here|[DataFrameReader.json|https://github.com/apache/spark/blob/v3.1.1/sql/core/src/main/scala/org/apache/spark/sql/DataFrameReader.scala#L432-L520]].
> Simiarly in the [Pyspark
> docs|[pyspark.sql.DataFrameReader.json|https://spark.apache.org/docs/latest/api/python/reference/api/pyspark.sql.DataFrameReader.json.html?highlight=json#pyspark.sql.DataFrameReader.json]]

> However we have this blurb in the [migration guide|[Spark 3.0 to 3.0.1
> migration
> guide|https://spark.apache.org/docs/latest/sql-migration-guide.html#upgrading-from-spark-sql-30-to-301]]
> * In Spark 3.0, JSON datasource and JSON function {{schema_of_json}} infer
> TimestampType from string values if they match to the pattern defined by the
> JSON option {{timestampFormat}}. Since version 3.0.1, the timestamp type
> inference is disabled by default. Set the JSON option {{inferTimestamp}} to
> {{true}} to enable such type inference.
> We should add this in the documentation as well as there is a possibility
> that the Data Engineers might not be aware of this option.
