title: Reading Time column in R
body: <p>I am reading a Excel file with time as a column.</p>
  
  <p>This column has values like </p>
  
  <pre><code>23:29:04
  23:04:31
  21:55:37
  21:52:27
  21:49:53
  </code></pre>
  
  <p>When I read this column using R , read column comes as a numeric value :</p>
  
  <pre><code>0.961469907
  0.913622685
  0.911423611
  0.907094907 
  0.906250000 
  0.899490741
  </code></pre>
  
  <p>There is no correspondence between above mentioned Excel and R column values. These are just samples.</p>
  
  <p><strong>I tried using</strong></p>
  
  <pre><code>strptime(TimeStamp,format="%H:%M:%S)
  </code></pre>
  
  <p>It gives all values as <code>NA</code>.  </p>
  
  <p>Please suggest how to read time correctly in R.</p>
