Why would you have the date set in the constructor?

Probably a random question, but I actually set the Date within the object Treet's constructor, that way, as you said it was immutable, and only when constructing a tweet would it be generated, and I would know that the creation date would be immutable and represent the date created within any system. I knew that Date() would get the now, I just think it can be dangerous to have a field where the programmer gets control of the logic for creation dates, i.e. more open to error than a sealed system. Thoughts?

I think that it is just for the sake of example, since the Treets aren't being created in real time(or at least not at the same time as the tweets), so we need to set it to a date in the past.

I Understand what you are saying, but surely this is more of an argument for importing Treets into the database and simply having them hydrate the Treet class, or another data-type?
