[Moo] Help - can't parse UK date

[mike taylor]

Probably being daft, but I can't det the moo-more to correctly parse a UK 
date/time.
 
I download moo-more with en-GB date locale, and here is a snippet of my 
code.
 

var val = '28/05/2012 17:34';
 
Locale.set("en-GB");

var d = new Date();

d.parse(val);

Any suggestions as to where I am going wrong. Ideally, I would like to 
parse and specify the date format, but can't see how to do that.

regards

Mike
