Instruction :
Does spark provide date & time when a particular event is received in the structured streaming?

Response:
Not directly.  The source of the data is responsible for event time, the “arrival” time is typically the timestamp from the message server source you are reading from (Kafka, Kinesis, etc.) and the “processing” time can be inserted when processing the incomming data stream using the functions package current_timestamp function. https://spark.apache.org/docs/latest/api/scala/index.html#org.apache.spark.sql.functions$  This isn’t exactly when Spark received the data from the server but is close and will be grouped by trigger interval.  Note that this function can not be used when in continuous mode.  https://spark.apache.org/docs/latest/structured-streaming-programming-guide.html#supported-queries
