Yes, because if input type=datetime then gets introduced differently
we have a legacy problem.

How many times do I have to say THIS HAS NOTHING TO DO WITH
VALIDATION, it is completely orthogonal to the problem.  creating a
date from Month/Year/date is considerably easier than creating one
from a single string - you must see this.  And because of regional
differences in how dates are entered, it means it's not even safe to
parse a date from a string, unless you know the format entered.

Yep, I couldn't find a single one that remotely came close, you said
you'd just found some before that were good, but chose a woeful one
simply because it was short.

As I say, I don't believe it can be done in under 10 lines, in fact
I'm incredibly confident of it.  Dean is a very good scripter, maybe
he'll rise to your challenge, but I'm willing to bet he won't be able
to do it.

Which is an ECMAScript requirement, it's also been implemented
behaviour in all script agents I've ever seen, could you suggest one
where it doesn't work?

I'm not that sure of syntax, I've described what I feel is necessary
in terms of functionality.

Jim.
