Custom Field Type - Fomalicious: Date/Time Stamp

Hey all, I have found a few tutorials on creating custom field types for formalicious. I’m looking to not recreate the wheel and add that functionality into my forms. I want to put a button as the selection for the line in the form that time stamps it, and have formalicious record it as part of the form, just as it would the text are, radio button, checkbox, etc. Thoughts? Has anyone tried this before? Can I do it with just a chunk? Thanks for listening!
