title: Dealing with date format in zoo
body: <p>I've a <a href="https://drive.google.com/file/d/0Bwfiy4mPaO61SnpOUWp3MmJKLUU/view?usp=sharing" rel="nofollow noreferrer">csv data file</a>  with the following formats
  <a href="https://i.stack.imgur.com/8T4lP.png" rel="nofollow noreferrer">Stock prices over the period of Jan 1, 2015 to Sep 26, 2017</a></p>
  
  <p>Now I use the following code to import the data as zoo object:</p>
  
  <pre><code>sensexzoo1&lt;- read.zoo(file = "/home/bidyut/Downloads/SENSEX.csv", 
                             format="%d-%B-%Y",  header=T, sep=",")
  </code></pre>
  
  <p>It produces the following error: </p>
  
  <blockquote>
    <p>Error in read.zoo(file = "/home/bidyut/Downloads/SENSEX.csv", format =
    "%d-%B-%Y",  :    index has 679 bad entries at data rows: 1 2 3 4 5 6
    7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
