Apparently, ` new Date() ` reads it correctly, though problems
can occur if the browser returns only two digits for the year.
In particular, time zone, field order and separators may vary.
It is also reliant on the server's clock having been correctly
set at the time of upload. See the URL

If it is agreed that newer browsers return four-digit years, then I
suggest changing :

can occur if the browser returns only two digits for the year.

to :
can occur for older browsers returning only two-digit years.

Do all newer browsers consistently include offset-from-GMT indication;
and, if any do not, do they consistently give the time in one of GMT,
user's local?

And then change it back if a new browser comes out with a bug that
returns a two-digit year?

Do you seriously think .... that even Merkin browser-writers would be
that stupid?

On the same basis you should restore the older Trim code, since RegExps
might get omitted or broken.

However, if you read what I wrote with due care, you should see that
"can occur for older browsers returning only two-digit years" refers
only to older browsers, and would remain true if new browsers appeared
with two-digit years. It would then be clear to the intelligent reader
that the new browsers would in this respect behave as the older ones.
