Question marked as
Just import the photo into the library and bring up the thumbnail's info window, ⌘+i. The date will be shown in the Info window. If you look in the Imports view it will be listed by date imported. In the Library/All Photos view it will be listed by date taken with the newest at the bottom of the window and the oldest at the top.
Importing does not change the date the photo was created.
