Bug Description

Reproducible Example

import { SequelizeModule } from '@nestjs/sequelize';
...
SequelizeModule.forRoot({
      timezone: "+08:00"
    })

I set some datas to database, and this frame will auto write 'createAt' to database.
The data 'createAt' set to database is in correct timezone
But when I use

import { Model } from 'sequelize-typescript';
...
const {createAt } = await model.findOne({
      where: {
        id,
      },

The 'creatat' time zone is still initial

What do you expect to happen?

The findOne or other's methods can find right timezone in 'createAt'

What is actually happening?

The 'createAt' timezone is still inital

Environment

• Sequelize version:
• Node.js version:
• If TypeScript related: TypeScript version:
• Database & Version:
• Connector library & Version:

Start by reproducing the shown SequelizeModule timezone configuration and model.findOne call, then gather the missing Sequelize, Node.js, database, and connector versions. Compare the stored and retrieved createAt values; the issue is done when the retrieved timestamp uses the intended timezone.
