Expected parameter scala.Option<Timestamp> vs. Actual argument Timestamp

This is probably a very silly question, but I have a case class which takes as a parameter Option[Timestamp]. The reason this is necessary is because sometimes the timestamp isn't included. However, for testing purposes I'm making an object where I pass in

Timestamp.valueOf("2016-01-27 22:27:32.596150")

But, it seems I can't do this as this is an actual Timestamp, and it's expecting an Option.

How do I convert to Option[Timestamp] from Timestamp. Further, why does this cause a problem to begin with? Isn't the whole benefit of Option that it could be there or not?

Thanks in advance,

Option indicates the possibility of a missing value, but you still need to construct an Option[Timestamp] value. There are two subtypes for Option - None when there is no value, and Some[T] which contains a value of type T.

You can create one directly using Some:

Some(Timestamp.valueOf("2016-01-27 22:27:32.596150"))

or Option.apply:

Option(Timestamp.valueOf("2016-01-27 22:27:32.596150"))
