Skuid UI Field Formula: Unix (epoch) Timestamp to DateTime

I’m looking to convert a UNIX timestamp (ie. 1487949382) to a DateTime field via a UI-Only Formula field. The REST model I’ve created returns only unix stamps and I need them to be human readable.

Before any script kitties jump in and offer up a .js snippet, I’m aware that’s possible. I’m just interested in how one might accomplish this with a skuid formula.
