title: Python Excel date/time read in issue
body: <p>I am trying to read dates/time off an excel sheet using Python, but I only want to read in the time so I can perform computations on it. For example if I have a date in the format: <code>3/11/2003  4:03:00 AM</code>
  on my excel sheet how can I read in just the <code>4:03:00</code> in Python? I ultimately want to be able to subtract hours, mins, or seconds from the read in time.</p>
