Hi,
~
I am parsing some data from archived files out of Unix file system
listings
~
The thing is that I decided to store the date as a long since the
Epoch, so that people from any locales can see it accordingly by a
simple reformatting on the fly
~
But, when I parse the date data, such as "Nov 10 2003" and build a
Calendar Object:
~
System.out.println("// __ aYr: |" + aYr + "|");
System.out.println("// __ aMonth: |" + aMonth + "|");
System.out.println("// __ aDayOfMonth: |" + aDayOfMonth + "|");
// __
   try{
    int iYr = Integer.parseInt(aYr);
    int iMnth = HMKMIx.get(aMonth.toUpperCase());
    int iDay = Integer.parseInt(aDayOfMonth);
System.out.println("// __ |" + iYr + "|" + iMnth + "|" + iDay + "|");
// __
    Calendar Kal = Calendar.getInstance();
    Kal.set(Calendar.YEAR, iYr);
    Kal.set(Calendar.MONTH, iMnth);
    Kal.set(Calendar.DAY_OF_MONTH, iDay);
// __ http://java.sun.com/javase/6/docs/api/java/util/Calendar.html#time
    Date Dt = Kal.getTime();
System.out.println("// __ Dt: |" + Dt + "|");
    lTm = Dt.getTime();
System.out.println("// __ lTm: |" + lTm + "|");
// __
   }catch(NumberFormatException NFX){
~
using:
~
   HMKMIx = new HashMap<String, Integer>();
   HMKMIx.put("JAN", Calendar.JANUARY);
   HMKMIx.put("FEB", Calendar.FEBRUARY);
   HMKMIx.put("MAR", Calendar.MARCH);
   HMKMIx.put("APR", Calendar.APRIL);
   HMKMIx.put("MAY", Calendar.MAY);
   HMKMIx.put("JUN", Calendar.JUNE);
   HMKMIx.put("JUL", Calendar.JULY);
   HMKMIx.put("AUG", Calendar.AUGUST);
   HMKMIx.put("SEP", Calendar.SEPTEMBER);
   HMKMIx.put("OCT", Calendar.OCTOBER);
   HMKMIx.put("NOV", Calendar.NOVEMBER);
   HMKMIx.put("DEC", Calendar.DECEMBER);

I am getting inconsistent results

I am using a Date object in order to get the time in millis because
the calendar class doesn't give ti to you directly
~
Why on earth is that happening? Even if they are just a few
milliseconds apart it should not be happening?
~
Is it possibly, obviously a bug or another homely and unspecified
semantics from java's date/calendar/time handling?
~
Thanks
