Well, yes, you are getting the current date and time. And also the default time zone. You can see all of that in your output, which is simply the result of calling the toString() method of the Calendar object. Which by the way is an instance of java.util.GregorianCalendar; toString() tells you that as well.
Of course if you want to work with the Calendar and do things like find out whether it's Saturday or the last day of the month or whether it's more than 30 days after the invoice you have elsewhere in your code, then you can call other methods of the Calendar to do that. You wouldn't use toString() for that purpose.
