I'm working on a API built using service repository pattern. For example when a request gets received , the controller passes data to service , then the service passes data to repository and repository gets data from database and sends it back to service and service returns data to controller, Here is the controller code :

[HttpGet("LatestNAV")]
public IActionResult GetLatestNAV()
{
    return Ok(_service.GetLastDailyNAV());
}

service:

public LastDailyNAVDto GetLastDailyNAV()
{
    var result = _repository.GetLastDailyNAV();
    return result.Adapt<LastDailyNAVDto>();
}

repository:

public LastDailyNAV GetLastDailyNAV()
{
    return _db.LastDailyNAV.OrderByDescending(n => n.date).FirstOrDefault();
}

I want to change the date retrieved from database in LastDailyNAV because its unformatted. My question is where is the best place to modify the date. I know that its not in repository cause its not repositories concern. But my problem is formatting data in service cause skinny controller and fat service and vice versa.
