## What changes were proposed in this pull request?
Timestamps data would loss prescision when doing broadcast serialization.
```
import org.apache.spark.sql.functions.expr
import org.apache.spark.sql.catalyst.expressions._
spark.range(0, 5).toDF("id").createOrReplaceTempView("target")
spark.range(0, 10)
.toDF("id")
.withColumn("timestampOne", expr("timestamp_micros(id)"))
.withColumn("timestampTwo", expr("timestamp_micros(id)"))
.createOrReplaceTempView("source")
spark.sql("SELECT unix_micros(source.timestampOne) FROM source RIGHT OUTER
JOIN target ON target.id = source.id").show(false)
```
Wrong result:
```
+-------------------------+
|unix_micros(timestampOne)|
+-------------------------+
|0 |
|0 |
|0 |
|0 |
|0 |
+-------------------------+
```
Expected result:
```
+-------------------------+
|unix_micros(timestampOne)|
+-------------------------+
|0 |
|1 |
|2 |
|3 |
|4 |
+-------------------------+
```
