How can I get an Ecto.DateTime value representing the current time?

I want to get an Ecto.DateTime value that represents the current time.

How can I do that?

Solution

  • While DateTime.utc_now |> Ecto.DateTime.cast works, there is a simpler way with Ecto.DateTime.utc

    It's basically the same but with a different default precision:

    iex(30)> DateTime.utc_now |> Ecto.DateTime.cast
{:ok, #Ecto.DateTime<2016-09-27 19:55:38.542000>}

iex(31)> Ecto.DateTime.utc
#Ecto.DateTime<2016-09-27 19:55:45>

iex(32)> Ecto.DateTime.utc(:usec)
#Ecto.DateTime<2016-09-27 19:55:48.162000>
