Can we do this like:
```scala
case (LONG, TimestampType) => avroType.getLogicalType match {
case _: TimestampMillis => (updater, ordinal, value) =>
updater.setLong(ordinal, value.asInstanceOf[Long] * 1000)
case _: TimestampMicros => (updater, ordinal, value) =>
updater.setLong(ordinal, value.asInstanceOf[Long])
case _ => (updater, ordinal, value) =>
updater.setLong(ordinal, value.asInstanceOf[Long] * 1000)
}
```
? Looks they have Avro long type anyway. Thought it's better to read and
actually safer and correct.
