Represents default values that are automatically generated by the database. As it happens, ISO-8601 is substantially similar to, but not identical to RFC 3339: Pretty much, yes - RFC 3339 is listed as a profile of ISO 8601.

To define a composite type, use the type block. However, if you need variations of the User type you can still define them using some of Prisma Client's generated helper types (in this case, these helper types would be called UserGetIncludePayload and UserGetSelectPayload). You can use prisma db pull to infer the correct value to resolve the discrepancy. In the following example, the value of the email field must be unique: In the following example, a combination of authorId and title must be unique: Constraint names in relational databases See Using custom model and field names to see how @map and @@map changes the generated Prisma Client. then you can pass a string to the time field.
