title: Convert UTC date into milliseconds
body: <p>I am not interested in what the current UTC time is in milliseconds, nor do I need to mess with timezones. My original date is already stored as a UTC timestamp.</p>
  
  <p>I have a date stored in a database in UTC time, "2012-06-14 05:01:25".
  I am not interested in the datetime, but just the date portion of the it. So, after retrieving the date in Java, and excluding the hours, minutes, and seconds - I am left with "2012-06-14".</p>
  
  <p>How can I convert this into UTC milliseconds?</p>
