[FEATURE] Timestamps should be customizable to use JSON date instead of epoch

Summary:

The automatic timestamps is a nice feature, but it would be nice if you could use another format such as JSON dates.

Suggestion for an extension to the options to allow for custom formatting:

{
  timestamps: {
    createdAt: 'createdTime',
    updatedAt: 'modifiedTime',
    format: ms => new Date(ms).toJSON()
  },
}

For even simpler configuration, the type of format could be e.g. "ms" | "json" | (ms: number) => any, so that you could use format: 'json'

I have the same issue. I use AWS amplify to generate the data models. In my bussiness logic, I must create the custom mutations or queries, I use lambda as datasources. The amplify use ISO string for AWSDateTime. In my solution, Insteads Date, I use String and convert String to Date. I hope the dynamoose can be custom the timestamps.

@henhal Totally fair. Appreciate the discussion. Just to be clear and make sure I understand, this is primarily for viewing the data in the DynamoDB Console or other 3rd party tools, correct? Because within your application you can easily do toJSON as you mentioned. So that is why I was misunderstanding the use case here. It’s specifically related to viewing the raw data?
