calendar

Suppose the following code is executed on the 22nd of August 2009 (a Saturday)

   Calendar c = Calendar.getInstance();
   c.set(Calendar.DAY_OF_WEEK, Calendar.SUNDAY);

c.get(Calendar.DAY_OF_MONTH) will return 23. I'm interested in the conditions is would return 14 (last Sunday, rather than the next Sunday).

Are there any rules associated with the direction Calendar will roll the DAY_OF_MONTH/YEAR when DAY_OF_WEEK is set? If so what are they?
