Safari Java Date Implementation

Question

Dear, I'm having this very strange problem at work today concerning dates. It seems that any dates beyond the 28th of February 2034 are being miscalculated and this happens only in Safari. It seems that starting from this date, the system calculates the date minus 1. I have absolutely no clue why this is or how this is possible. Is there something different after the 28th of February 2034? Maybe it has something to do with a leap year or am I doing something wrong in my javascript code? Any advice would be highly appreciated. I'll leave a code example below illustrating this problem. Pay attention to date 4 and 5, these one will produce 11th of October instead of 12th of October.
<script type="text/javascript">
function TestDates() {
var date1 = '10/12/2010';
var date2 = '10/12/2020';
var date3 = '10/12/2030';
var date4 = '10/12/2040';
var date5 = '10/12/2050';
alert(date1);
alert(date2);
alert(date3);
alert(date4);
alert(date5);
var dat1 = new Date(date1);
var dat2 = new Date(date2);
var dat3 = new Date(date3);
var dat4 = new Date(date4);
var dat5 = new Date(date5);
alert(dat1);
alert(dat2);
alert(dat3);
alert(dat4);
alert(dat5);
</script>

I assume you meant Javascript and not Java here, but I am having the same problem too.
I have found a workaround. Bascially you  just need to specify the time explicitly as well as the date. In your case, just append a " 00:00" (note the space) to your date strings in your constructor calls and the bug is avoided.
Haven't tried it in Safari for Windows, but I can attest that the same bug occurs in the Mac version as well, so I hope my workaround will work in windows too.
