Getting time from Calendar

[John Faulk]

hi, i am trying to figure out if the time has been set in the calendar. isSet returns true if the hour is 0 assuming it is midnight. so when does it return false.
-----------------------------------------------------------
Calendar c = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd");
Date d = sdf.parse("20010909", new ParsePosition(0));
System.out.println("t/f " + c.isSet(Calendar.HOUR) );
-----------------------------------------------------------
the above returns true because the hour is 0. so when will it return false???

yes i did do a c.setTime(d); after getting Date d.

Per the API

isSet()
The flags which tell if a specified time field for the calendar is set. A new object has no fields set. After the first call to a method which generates the fields, they all remain set after that. This is an array of FIELD_COUNT booleans, with index values ERA through DST_OFFSET.
