How best to do a once only calculation?

We have a need to put in a date generated when you construct the form as
such I have looked at

<xforms:bind nodeset="Date_begun" id="Date_begun" type="xsd:dateTime"
calculate="now()" />

However rather obviously it will do this everytime I open this
element/form.

We have an element which can carry a value which we are using to denote
if something is new (i.e. should have the date now() generated) or
already existing i.e. it should be left as is.


Any ideas?

TIA


Adam
