Truncate this date, leaving the field specified as the most significant field.

For example, if you had the datetime of 28 Mar 2002 13:45:01.231, if you passed with HOUR, it would return 28 Mar 2002 13:00:00.000.

Usage

From source file:DateUtilsV1.java

 public static void main(String args[]) {

   System.err.println("Original Date: " + date);
   System.err.println("Rounded Date: " + DateUtils.round(date, Calendar.HOUR));
   System.err.println("Truncated Date: " +   DateUtils.truncate(date, Calendar.MONTH));

   Iterator itr = DateUtils.iterator(date, DateUtils.RANGE_WEEK_MONDAY);

   while(itr.hasNext()) {
      System.err.println(((Calendar)itr.next()).getTime());
   }/*from   w  w w  . java2s  .  c o  m*/
