title: crystal reports date formatting
body: <p>I'm using Crystal Reports.</p>
  
  <p>I have a report where user enters date in yyyy-mm-dd format(for ex- <code>1999-12-31</code>)..</p>
  
  <p>using crystal reports formulae, how can I change the format to 
  <code>1999-12-31 00:00:00.0</code>?</p>
  
  <p>Is there any function like <code>to_timestamp({?start_date}, yyyy-mm-dd hh:mm:ss)</code>?</p>
