如何创建带时间戳的spark数据帧

import org.apache.spark.sql.SparkSession
import org.apache.spark.sql.functions._
import org.apache.spark.sql.types._

val spark = SparkSession.builder()
  .appName("Creating DataFrame with Timestamp")
  .getOrCreate()

val schema = StructType(Seq(
  StructField("id", IntegerType, nullable = false),
  StructField("value", StringType, nullable = false),
  StructField("timestamp", TimestampType, nullable = false)
))

val data = Seq(
  (1, "A", java.sql.Timestamp.valueOf("2022-01-01 10:00:00")),
  (2, "B", java.sql.Timestamp.valueOf("2022-01-01 11:30:00")),
  (3, "C", java.sql.Timestamp.valueOf("2022-01-01 13:15:00"))
)

val rdd = spark.sparkContext.parallelize(data)
val df = spark.createDataFrame(rdd, schema)
