Parsing json date and time

Question

I am trying to parse Datetime in revel from a json request. The query looks something like this:

{
  "startedAt": "2017-06-01 10:39",
  ...
}

The structure that it decodes is as follows:

type MyStruct struct {
  StartedAt time.Time `json:"startedAt" bson:"startedAt"`
  ...
}

The decoding line is as follows:

json.NewDecoder(c.Request.Body).Decode(&MyStruct)

Revel returns this error:

interface conversion: error is *time.ParseError, not *errors.Error

According to revel documentation, https://revel.imtqy.com/manual/parameters.html

The SQL standard date time formats of 2006-01-02, 2006-01-02 15:04 are built in.

In the same document, they also say that you can add formats like this:

func init() {
    revel.TimeFormats = append(revel.TimeFormats, "01/02/2006")
}

To verify that the format was in an array, I tried this:

func init() {
    revel.TimeFormats = append(revel.TimeFormats, "2016-06-01 12:12")
}

In my last despair, I tried to present it in the same format as revel would return json once in:

{
  "startedAt": "2017-06-22T12:22:16.265618819-05:00",
  ...
}

At this moment, I'm not sure where to go with this. Could anyone enjoy using Datetime analysis?

Update: I tried the RickyA solution below, but now there is a parsing error.

parsing time ""Mon, 02 Jan 2006 15:04:05 -0700"" as "Mon, 02 Jan 2006 15:04:05 -0700": cannot parse ""Mon, 02 Jan 2006 15:04:05 -0700"" as "Mon"
