altFormat doesn't work clicking "Done"

[twinklebob]

Apologies if this has been recorded before.

I'm using version 0.9.3.

I want to display a pretty format to the user:
dateFormat: 'DD, d MM yy', timeFormat: 'hh:mm',

And store an equivalent timestamp in a hidden field (for processing), so have used:
altFormat: '@'

This seems to work if I select a date and hit 'Esc'. But if I select a date and click "Done" the pretty format is put into the hidden field.

Why? How can I enforce the use of the AltFormat?

Sorry I posted #226 issue on same subjects.

Use

altFieldTimeOnly: false

And apply this patch to v1.0.0
