[SOLVED] Java Calendar adds a random number of milliseconds?

Java Calendar adds a random number of milliseconds?

Hi I have something weird happening. I am simply taking a calendar object, converting it to its individual parts, and putting it back into a calendar (with or without any changes. In this case I make no changes). I mean, this should be cut and paste. I've also tried to create a calendar with calendar = Calendar.getInstance() and set everything manually. calendar.set(Calendar.YEAR, mStartYear); so on. Still gives wrong Calendar objects. I've tried also setting Milliseconds, always seem to have some garbage milliseconds.. But the time one way or another just is completely off. Maybe someone sees the stupid oversight, but I'm stumped.

Also this is an android application, but shouldn't matter for a basic Java library object.

Note Weekview is a datawrapper for one of the libraries I'm using. It has a start and an end calendar.

Here is what the debugger lists as in memory..

mEndDay = 19
mEndHour = 9

mEndMinute = 30
mEndMonth = 8
mEndYear = 2015
mSeekAmount = 0
mStartDay = 18
mStartHour = 23
mStartMinute = 0
mStartMonth = 8
mStartYear = 2015


            Calendar calendarStart = Calendar.getInstance();
            calendarStart.set(mStartYear,mStartMonth,mStartDay,mStartHour,mStartMinute);

            Calendar calendarEnd = Calendar.getInstance();
            calendarEnd.set(mEndYear,mEndMonth,mEndDay,mEndHour,mEndMinute);

I end up with

Start 1442363359161
End 1442363359161

calendarStart = {GregorianCalendar@20968} "java.util.GregorianCalendar[time=?,areFieldsSet=false,lenient=true,zone=America/Denver,firstDayOfWeek=1,minimalDaysInFirstWeek=1,ERA=1,YEAR=2015,MONTH=8,WEEK_OF_YEAR=38,WEEK_OF_MONTH=3,DAY_OF_MONTH=18,DAY_OF_YEAR=258,DAY_OF_WEEK=3,DAY_OF_WEEK_IN_MONTH=3,AM_PM=1,HOUR=6,HOUR_OF_DAY=23,MINUTE=0,SECOND=19,MILLISECOND=161,ZONE_OFFSET=-25200000,DST_OFFSET=3600000]"
calendarEnd = {GregorianCalendar@20969} "java.util.GregorianCalendar[time=?,areFieldsSet=false,lenient=true,zone=America/Denver,firstDayOfWeek=1,minimalDaysInFirstWeek=1,ERA=1,YEAR=2015,MONTH=8,WEEK_OF_YEAR=38,WEEK_OF_MONTH=3,DAY_OF_MONTH=19,DAY_OF_YEAR=258,DAY_OF_WEEK=3,DAY_OF_WEEK_IN_MONTH=3,AM_PM=1,HOUR=6,HOUR_OF_DAY=9,MINUTE=30,SECOND=19,MILLISECOND=161,ZONE_OFFSET=-25200000,DST_OFFSET=3600000]"

EXPECT

Start 1442638800000
End 1442676600000

mEndTime = {GregorianCalendar@20990} "java.util.GregorianCalendar[time=1442676600000,areFieldsSet=true,lenient=true,zone=America/Denver,firstDayOfWeek=1,minimalDaysInFirstWeek=1,ERA=1,YEAR=2015,MONTH=8,WEEK_OF_YEAR=38,WEEK_OF_MONTH=3,DAY_OF_MONTH=19,DAY_OF_YEAR=262,DAY_OF_WEEK=7,DAY_OF_WEEK_IN_MONTH=3,AM_PM=0,HOUR=9,HOUR_OF_DAY=9,MINUTE=30,SECOND=0,MILLISECOND=0,ZONE_OFFSET=-25200000,DST_OFFSET=3600000]"
mName = {String@20991} "sleep"
mStartTime = {GregorianCalendar@20992} "java.util.GregorianCalendar[time=1442638800000,areFieldsSet=true,lenient=true,zone=America/Denver,firstDayOfWeek=1,minimalDaysInFirstWeek=1,ERA=1,YEAR=2015,MONTH=8,WEEK_OF_YEAR=38,WEEK_OF_MONTH=3,DAY_OF_MONTH=18,DAY_OF_YEAR=261,DAY_OF_WEEK=6,DAY_OF_WEEK_IN_MONTH=3,AM_PM=1,HOUR=11,HOUR_OF_DAY=23,MINUTE=0,SECOND=0,MILLISECOND=0,ZONE_OFFSET=-25200000,DST_OFFSET=3600000]"

Here is where I set it up initially..

   WeekViewEvent weekViewEvent = dateWrapperParam.getWeekViewEvent();
    Calendar endCalendar = weekViewEvent.getEndTime();
    Calendar startCalendar = weekViewEvent.getStartTime();

    Date endDate = endCalendar.getTime();
    Date startDate = startCalendar.getTime();

    mStartHour = startCalendar.get(Calendar.HOUR_OF_DAY);
    mStartMinute = startCalendar.get(Calendar.MINUTE);
    mStartDay = startCalendar.get(Calendar.DAY_OF_MONTH);
    mStartMonth = startCalendar.get(Calendar.MONTH);
    mStartYear = startCalendar.get(Calendar.YEAR);

    mEndHour = endCalendar.get(Calendar.HOUR_OF_DAY);
    mEndMinute = endCalendar.get(Calendar.MINUTE);
    mEndDay = endCalendar.get(Calendar.DAY_OF_MONTH);
    mEndMonth = endCalendar.get(Calendar.MONTH);
    mEndYear = endCalendar.get(Calendar.YEAR);

Solution

As per my comments under your question , there is only difference in seconds and milliseconds between startCalendar and calendarStart time, because that values were not reset.
