javaScript add the system file creation date

Hi,

I have a javascript for my pdf and I want to insert the creation date into a form field. 

I was able to get the Modified date that you can see in Acrobat under tthe File->Properties->Description tab with 

this.info.CreationDate;

However I want to get the creation date under the system file properties (right click on the pdf->Properties).

Is this possible?

Thanks!
