What is the default timezone for java.util.Calendar.?

Code

public String testDate(){ 
      TimeZone.setDefault(TimeZone.getTimeZone("US/Eastern"));
      Calendar fromDate = Calendar.getInstance();
      Date date= new Date();
      System.out.println(fromDate);
      System.out.println(date);
}

My calendar variable shows a cdate value 2013-12-09T00:00:00.000Z and time value 1386649779590 while debugging the calendar variable below.

Calendar cal = Calendar.getInstance();

Complete Calendar details which i have seen while printing the object

System.out.println(cal);

Console

java.util.GregorianCalendar[time=1386649779590,areFieldsSet=true,areAllFieldsSet=true,lenient=true,zone=sun.util.calendar.ZoneInfo[id="US/Eastern",offset=-18000000,dstSavings=3600000,useDaylight=true,transitions=235,lastRule=java.util.SimpleTimeZone[id=US/Eastern,offset=-18000000,dstSavings=3600000,useDaylight=true,startYear=0,startMode=3,startMonth=2,startDay=8,startDayOfWeek=1,startTime=7200000,startTimeMode=0,endMode=3,endMonth=10,endDay=1,endDayOfWeek=1,endTime=7200000,endTimeMode=0]],firstDayOfWeek=1,minimalDaysInFirstWeek=1,ERA=1,YEAR=2013,MONTH=11,WEEK_OF_YEAR=50,WEEK_OF_MONTH=2,DAY_OF_MONTH=9,DAY_OF_YEAR=343,DAY_OF_WEEK=2,DAY_OF_WEEK_IN_MONTH=2,AM_PM=1,HOUR=11,HOUR_OF_DAY=23,MINUTE=29,SECOND=39,MILLISECOND=590,ZONE_OFFSET=-18000000,DST_OFFSET=0]

While my java.util.date variable shows a date as Mon Dec 09 07:37:50 EST 2013, while debugging the date variable

Date date= new Date();

where as my default timezone that i have set is EST specified on program start

TimeZone.setDefault(TimeZone.getTimeZone("US/Eastern"));

And i am working from a timezone IST.

My question is

Why is cal of Calendar and date of Date() different ?
