problem with date class

[gabriel]

Date dday1=new Date(2007,6,31);
Date dday2=new Date(2005,1,1);
long sDay1=dday1.getTime();
long sDay2=dday2.getTime();
System.out.println(""+sDay1+"---"+sDay2);

it returns to me ：1120147200000---1120147200000
why?

You should use the java.text.DateFormat object to print out your Date objects in a more readable format.

As for why here is the description of java.util.Date.getTime from the java docs
"Returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this Date object."
