Convert BigNum to Time object


I am trying to import data from an old database which stored timestamps
as int fields. I am looking for a way of turning them into a datetime
field created_at.

Let’s say for example that I have

OldArticle.time # BigNum 1111111111

And I would like:

NewArticle.created_at = ???(Old.Article.time)

How can I do that?

By the way, should I use timestamps or datetimes for created_at and
updated_at fields? I found both…

Thank you a lot!


How could I miss it… The answer is:

NewArticle.created_at =
