title: Best way to store date/time into core data
body: <p>For each course I am storing the day of the week the class the user has...and the start and end time and room no. 
  What would be the best approach in terms of data type, Like for storing time?? so that when I pull it out I can display it e.g 1:00 PM. </p>
  
  <p>Thanks! </p>
