Need to add date stamp to Document Template

[Rylie Markle]

Hello, 

I am looking to add a date stamp to a PDF Document template of the date/time the employee signature was completed. What is the best way to go about this? I have a field for Signature Date- can I use an advanced script? Any advice is appreciated. 

Thanks!

@Samaksh Wani/@Rylie Markle  - I need to fill in the Date in PDF when Subject Person signs the PDF document. I tried the above script but it is not working for me. I believe I am missing something. Can you please help me with the complete screenshot of the template mapping? Thanks in advance.
