+`int96_from_spark.parquet` is generated by Apache Spark 3.4.3 with parquet-mr version 1.13.1.
+
+It has a single column of int96 type with 6 values. int96 typically represents a timestamp with
+int32 representing the number of days since the epoch, and an int64 representing
+nanoseconds. Due to its nanosecond resolution, many systems handle int96 timestamps by
+converting the int32 days to nanoseconds and adding the two values to form a single
+64-bit nanosecond timestamp. However, Spark's default timestamp resolution is microseconds, which
+results in being able to read and write timestamps with a larger range of dates.
+
+Note that this type is now deprecated in the Parquet spec. It exists only for systems that wish
+to maintain compatibility with Apache Spark and other systems that still write this type.
+
+This file contains timestamps that are not all representable with 64-bit nanosecond timestamps.
+It originates from [a test for DataFusion Comet](https://github.com/apache/datafusion-comet/blob/fa5910efd927e115d1717b5f0c78fad0ece75c6c/spark/src/test/scala/org/apache/comet/CometCastSuite.scala#L902),
+and can be reproduced in a Spark shell with the code below:
+
+```scala
+val values = Seq(Some("2024-01-01T12:34:56.123456"), Some("2024-01-01T01:00:00Z"), Some("9999-12-31T01:00:00-02:00"), Some("2024-12-31T01:00:00+02:00"), None, Some("290000-12-31T01:00:00+02:00"))
+import org.apache.spark.sql.types.DataTypes
+val df = values.toDF("str").select(col("str").cast(DataTypes.TimestampType).as("a")).coalesce(1)
+df.write.parquet("int96_from_spark.parquet")
+```
+
+As microseconds since the epoch, they correspond to:
+```
+1704141296123456, 1704070800000000, 253402225200000000, 1735599600000000, null, 9089380393200000000
