is the date example correct?

Hi

I already wrote this mail once but noone responded. Maybe it got lost
or the people who know about it were in holidays. Now that Scott is
back I repost it. Sorry, but I really want to know that.

I have a problem with the date example. I computed it three different
languages and they all give the same result that is different than the
spec. All these languages tell me 2:51:31 May 8, 1998 is 894595891000
miliseconds since the epoch whereas the spec says it's 894621091000.

Here's my Java Code

               int[] specData = {0x00, 0x00, 0x00, 0xd0, 0x4b, 0x92,
0x84, 0xb8};
               long expected = 0;
               for (int i = 0; i < 8; ++i) {
                       expected <<= 8;
                       expected |= specData[i];
               }

               Calendar calendar = Calendar.getInstance();
               TimeZone utc = TimeZone.getTimeZone("UTC");
               calendar.setTimeZone(utc);
               calendar.set(YEAR, 1998);
               calendar.set(MONTH, MAY);
               calendar.set(DAY_OF_MONTH, 8);
               calendar.set(HOUR_OF_DAY, 2);
               calendar.set(MINUTE, 51);
               calendar.set(SECOND, 31);
               calendar.set(MILLISECOND, 0);

               System.out.printf("my result:%tQ\n", calendar.getTime());
               System.out.printf("spec: %d\n", expected);

               System.out.println("difference in milliseconds: " +
(expected - calendar.getTimeInMillis())); //25200000
               System.out.println("difference in hours : " +
(expected - calendar.getTimeInMillis()) / 1000 / 3600); //7

               long acutal = calendar.getTimeInMillis();
               int[] realData = new int[8];
               for (int i = 0; i < 8; ++i) {
                       realData[i] = (int) acutal & 0xFF;
                       acutal >>= 8;
               }
               System.out.printf("0x%02x 0x%02x 0x%02x 0x%02x 0x%02x
0x%02x 0x%02x 0x%02x", realData[7], realData[6], realData[5],
realData[4], realData[3], realData[2], realData[1], realData[0]);

Could you please tell me whether I or the spec is wrong (of both us).

The spec doesn't mention it but I don't suspect that leapseconds are counted.

And finally when playing around with the BasicAPI test I found out
that remotes can't be serialized (I sent a remote to echo and got a
fault as answer telling me it can't be serialized). Is there a special
reason that this is not allowed or is this just a limitation of the
Java implementation?

Cheers
Philippe
