in the behaviour of getYear() between Netscrape and
Exploder. The ideal solution is to use getFullYear(),
which returns the actual year number, but that would
break this code on versions of JavaScript prior to
1.2. So, for the moment we use the following code
which works for all versions of JavaScript and browsers
for all year numbers greater than 1000. When we're willing
to require JavaScript 1.2, this may be replaced by
the single line:
document.gregorian.year.value = today.getFullYear();
Thanks to Larry Gilbert for pointing out this problem.
