TimexPoison

Easily parse timestamps using Timex as they are decoded from json by Poison.

Installation

If available in Hex, the package can be installed as:

1. Add timex_poison to your list of dependencies in mix.exs:

def deps do
  [{:timex_poison, "~> 0.2.0"}]
end

2. Ensure timex_poison is started before your application:

def application do
  [applications: [:timex_poison]]
end

Usage

Basic Usage

By default, timestamps will be parsed using Timex's {ISOz} formatter.

defmodule MyGreatStruct do
  use TimexPoison keys: [:created_at]
  defstruct [:name, :created_at]
end

iex> Poison.decode! ~s({"name": "Great", "created_at": "2016-07-27T08:50:08.681Z"}), as: %MyGreatStruct{}
%MyGreatStruct{name: "Great", created_at: #<DateTime(2016-07-27T08:50:08Z)>} 

Formatter Selection

Alternatively you can specify your own formatter:

defmodule WithDateFormat do
  use TimexPoison, keys: [:timestamp], format: "{RFC1123}"
  defstruct [:timestamp]
end

iex> Poison.decode(~s({"timestamp" : "Tue, 05 Mar 2013 23:25:19 +0200"}), as: %WithDateFormat{})
