title: Return the earliest time for each day
body: <p>I have this set of data:</p>
  
  <pre><code>    A        B 
  1  1/1/15   6:05am
  2  1/1/15   10:00am
  3  1/2/15   6:10am
  4  1/2/15   11:58am
  </code></pre>
  
  <p>Data in column A is a valid Excel date field and data in column B is valid Excel time field.</p>
  
  <p>What I am trying to get is the time of the first call per day. Example:</p>
  
  <pre><code>1/1/15 6:05am
  1/2/15 6:10am
  </code></pre>
  
  <p>I have tried PivotTables with sort and groups but that did not work. Any ideas/suggestions are most welcome.</p>
