Possible crasher in Date class

Arthur thinks this might be a bug in the Date class.

The speakingclock applet seems to crash HotJava. The last time (see
console messages below), I had started up HotJava, got the time in
every language, and then went away for a while. As soon as I returned
to the page, HotJava crashed.

The time before, I think HotJava crashed after I clicked one of the
speakingclock applets -- I don't remember which one. It seemed kind
of random.

The speakingclock applet is at:
http://www/java.sun.com/applets/applets/speakingclock/

Oh, another bug I noticed (might be the class, might be the program)
is that once the time kept changing from 12:31 (the true time) to 19:31.
