updatedAt before createdAt

[kewp]

Bug description

I just started playing with prisma. In prisma studio I made a new record with the Example table. It is showing updatedAt as having happened before createdAt. Clearly this is incorrect. See screenshot below.

How to reproduce

I'm busy going through the T3 tutorial https://www.youtube.com/watch?v=YkOSUVzOAA4&t=412s

1. Create T3 app using create-t3-app
2. Change DATABASE_URL to PlanetScale url
3. Change schema.prisma to value below
4. Run npx prisma studio
5. Add new record to Example table
6. Note createdAt and updatedAt (see screenshot above)

Expected behavior

No response

Prisma information

// This is your Prisma schema file,
// learn more about it in the docs: https://pris.ly/d/prisma-schema

datasource db {
  provider = "mysql"
  url      = env("DATABASE_URL")
  relationMode = "prisma"
}

generator client {
  provider = "prisma-client-js"
}

model Example {
    id        String   @id @default(cuid())
    createdAt DateTime @default(now())
    updatedAt DateTime @updatedAt
}

import { PrismaClient } from "@prisma/client";

import { env } from "~/env.mjs";

const globalForPrisma = globalThis as unknown as { prisma: PrismaClient };

export const prisma =
  globalForPrisma.prisma ||
  new PrismaClient({
    log:
      env.NODE_ENV === "development" ? ["query", "error", "warn"] : ["error"],
  });

if (env.NODE_ENV !== "production") globalForPrisma.prisma = prisma;

Environment & setup

• OS: macOS
• Database: PlanetScale
• Node.js version: v18.15.0

Prisma Version

I can confirm it on 5.9.0-dev with the provided schema, but only when using Studio to create the records - prisma.example.create({ data: {} }) on the other hand returns identical timestamps.
