Hi Bill,

Thanks for your email. I agree that the template seems like a good place 
for this, but to give a little extra detail.

I have a form that is used for both object create and editing. When I 
edit an object I have this in my controller:

$c->stash(formdata => $object);

and in the template:

<input name="datefield" type="text" value="[% 
formdata.datefield.dmy('/') %]" />

But when creating a new object, if the form validation fails I pass the 
form data back to the form like so:

$c->stash( formdata => $c->request->params );

But now the datefield is a text string and formdata.datefield.dmy('/') 
prints blank.

I was thinking that if I could define my DateTime stringification to my 
required format centrally then I could just use this in the template

<input name="datefield" type="text" value="[% formdata.datefield %]" />

and both scenarios would be happy.

Is the only way to do this to put more code in the template?

Thanks again for your help
