Generate time.Time from string/date-time

Would it be possible to generate a Go time.Time type from schema string/date-time? Example:
```
    "start_date": {
      "description": "The actual start date",
      "type": "string",
      "format": "date-time"
    }
```
currently creates 
```
StartDate string `json:"start_date"`
```
but in our case we would prefer
```
StartDate time.Time `json:"start_date"`
```
