Scala conversion long to datetime

Question

I am using nscala-time (wrapper for Joda Time) and slick for a project. I\'m trying to use this clause to write a line to the database:

Article.insert(0,\"ti

There's no magic about it. Your first statement:

DateTime.now.getMillis

is a Long. A Long is not a Timestamp, so it makes sense that you can't convert it to one by using asInstanceOf.

The second statement:

new Timestamp(dateTime.getMillis())

is using the Timestamp constructor to create a new Timestamp instance based on the dateTime.getMillis.
