title: Avoiding default date value to be used when only time is provided to a datetime field on Redshift
body: <p>I created a table with a datetime field "dt". Using COPY command to load data. The corresponding value for the field from the file is just the hour information, i.e., say, 14:50:00. So, the value being stored is 1900-01-01 14:50:00. I don't need the date part. How to do that. </p>
  
  <p>Or may be an alternate datatype which can store only time.</p>
