如何从pyspark中的时间戳中提取时间？

from pyspark.sql import SparkSession
from pyspark.sql.functions import hour, minute, second

spark = SparkSession.builder.getOrCreate()

data = [("2022-01-01 10:30:45"), ("2022-01-01 15:45:20")]
df = spark.createDataFrame(data, ["timestamp"])

df = df.withColumn("hour", hour(df.timestamp))
df = df.withColumn("minute", minute(df.timestamp))
df = df.withColumn("second", second(df.timestamp))

df.show()
