Examples of java.util.Calendar.clear()

java.util.Calendar.clear()
Sets the given calendar field value and the time value (millisecond offset from the Epoch) of this Calendar undefined. This means that {@link #isSet(int) isSet(field)} will return false, andthe date and time calculations will treat the field as if it had never been set. A Calendar implementation class may use the field's specific default value for date and time calculations.
The {@link #HOUR_OF_DAY}, {@link #HOUR} and {@link #AM_PM}fields are handled independently and the the resolution rule for the time of day is applied. Clearing one of the fields doesn't reset the hour of day value of this Calendar. Use {@link #set(int,int) set(Calendar.HOUR_OF_DAY, 0)} to reset the hourvalue. @param field the calendar field to be cleared. @see #clear()
