  - create
```
public static java.util.Date create(int day,
                                    int month,
                                    int year)
```
    With hour to 0. If day, month and year are 0 return null.
    The time zone is the default one, so if you print this date in the same JVM you will get the correct one. However, if you move the date object from one machine to other, or save it in a database that will be read from another locale maybe the dates will not match.
  - create
```
