Issues with Date fields on the Career Center Pages

Summary

I have two questions about including a date on the career center pages - see below

Content

We want to include the 'posted date' on the job search results page but the field does not appear to be an option when looking at the fields to add.  Is there a way to add this information? 

We are currently using the Last Updated date field (since that is our only option) - but this field is showing up as a datetime stamp so the time of the last update is included as well (7/14/2016 10:45 AM) which looks very odd.  Is there a way to change this format?  Thank you!
