User.UserData.LastAccessedDate relecting user creation date?

Hi all,

Has anyone else noticed that /d2l/api/lp/(version)/users/(userId) always returns a value for LastAccessedDate, even if the user has never logged in? The above snippet is for a user created late yesterday afternoon via the API, and we know the user has yet to access our Brightpace environment.
I'm wondering if this is by design (I don't think so as the docco states this value can be null), or if we're doing something at create time to cause this, or if this is a bug…
