title: Combining date and time in clojure to return an instant
body: <p>I have a date and time input as "2016-09-08" and "3:45 PM".
  I want to use clojure functions to return them as 2016 09 08 3 45</p>
  
  <p>I have used replace function to remove special characters and reduce to combine. But that becomes a string not an integer. I have tried using formatter function but didn't work.</p>
  
  <p>Can you help me out. </p>
