Date a Page was First Generated to Live?

We're implementing a Data Layer for use with Google Analytics and for News Articles we have a "dateFirstPublished" attribute on account on News Articles have an explicit date set by the editors:

https://www.nintendo.pt/Noticias/2016/Marco/Jogos-Wii-U-juntam-se-a-gama-Nintendo-Selects-a-15-de-abril-1091214.html

"dateFirstPublished": "2016-03-10",

For all other pages we don't have such an attribute but we would like to use the date a page was first generated to Live by Limelight.

Does anyone know if this kind of meta information is stored anywhere in FirstSpirit? We've not been able to find it ourselves.
