Prisma

What happened to the `createdAt` and `updatedAt` default fields?  Is there a different directive than `@model` that has those (with corresponding date creation/update behaviors)?

just add them yourself. Graphcool will set the values correctly for you

See here <https://www.graph.cool/docs/reference/database/data-modelling-eiroozae8u#writing-a-data-model>

```
type Tweet @model {  
  id: ID! @isUnique
  createdAt: DateTime!
  updatedAt: DateTime!
  text: String!
  owner: User! @relation(name: "UserOnTweet")
}
```

```
Optional system fields: createdAt and updatedAt
Graphcool offers two special fields that you can add to @model types:
- createdAt: DateTime!: Stores the exact date and time for when a node of this model type was created.
- updatedAt: DateTime!: Stores the exact date and time for when a node of this model type was last updated.
