WA19: using java's Date to calculate time difference is a mistake - it calculates it in not trivial way

I also had WA 19. There are some tricks to get AC in Java using java.util.Date. Take your tambourine and let's go!

1. Divide milliseconds count by 24*60*60*1000.
2. January's index is 0, not 1.
3. Use, for example, year-1500 instead of year.
4. Use Date's deprecated constructor.

You don't have to care about all those details.
Use GregorianCalendar it will take care everything for you.
