I have a timestamp coming back from a 3rd party package. I have read these articles and don’t see how to just store this value in my db and have it come back as some sort of date type in elixir.

https://hexdocs.pm/ecto/Ecto.Schema.html

1. is there an Ecto type that should just take in the timestamp and convert it?
2. do I need to convert it manually in the changeset? (that would seem strange)

The codes:

##My Timestamp##
DateTime.from_unix 1518960668
Yeah this is cool

##using :utc_datetime##

** (FunctionClauseError) no function clause matching in Ecto.Type.cast_naive_datetime/1

The following arguments were given to Ecto.Type.cast_naive_datetime/1:

    # 1
    1518960668

Attempted function clauses (showing 4 out of 4):

    defp cast_naive_datetime(%{year: empty, month: empty, day: empty, hour: empty, minute: empty}) when empty === nil or empty === ""
