title: Set current time in init ELM 0.19
body: <p>I get input JSON data from JS. This is a simple object, among which there is a date in the format "DD.MM.YYYY" - just a string.</p>
  
  <p>If there is no dateStart in the object, I have to replace it with the current date (in withDefault).</p>
  
  <pre><code>paramsDecoder : Decode.Decoder Params
  paramsDecoer =
      Decode.succeed Params
          |&gt; Decode.andMap (Decode.field "dateStart" (Decode.string) |&gt; (Decode.withDefault) "")
          |&gt; Decode.andMap (Decode.field "dateEnd" (Decode.string)   |&gt; (Decode.withDefault) "")
          |&gt; Decode.andMap (Decode.field "country" (Decode.string)   |&gt; (Decode.withDefault) "spain")
  </code></pre>
  
  <p>How can I do this in ELM?
  Timezone is not important and is always equal to the same region.</p>
  
  <p>I found an example of Time.now Time.zone usage, 
  but there time is getting in Update and its too late.</p>
