title: Excel Dates Formatting issue
body: <p>In Excel</p>
  
  <p>Whenever I try adding days to a date (for eg: 3/15/18 1:50 PM)
  the result gives me date with two spaces in between date and time. Tried formatting cells, trimming cells replacing space using substring, but nothing worked</p>
  
  <pre><code>Date            Days   New_date
  3/15/18 1:50 PM   0     3/15/18  1:50 PM
  </code></pre>
