node.js sequelize postgresql timezone Javascript

I'm sure I'm missing something obvious here, but I've searched everywhere and can't find a clear answer... I'm collaborating on a project where I'm currently working with an scenario with how dates are being stored in my PostgreSQL database when using Node.js with Sequelize. I have a model defined like this: ```javascript const Event = sequelize.define('Event', { name: { type: Sequelize.STRING, allowNull: false }, eventDate: { type: Sequelize.DATE, allowNull: false } }); ``` When I save an event with a specific date and time using UTC, I expect it to be saved correctly in the database, but when I retrieve it, the time seems to shift by several hours, which I believe is due to timezone handling. For example, if I store an event with `eventDate` set to `2023-10-10T12:00:00Z`, I end up fetching a date that appears to be `2023-10-10T08:00:00Z` instead. This leads to confusion in the application because it shows the wrong time to the users. I've tried explicitly setting the timezone in my Sequelize configuration: ```javascript const sequelize = new Sequelize('database', 'username', 'password', { host: 'localhost', dialect: 'postgres', timezone: 'UTC' // I expected this to help }); ``` However, I still see discrepancies when the data is retrieved. When I log the retrieved date with `console.log(event.eventDate)`, it shows the date adjusted for my local timezone instead. Additionally, I checked the PostgreSQL settings, and the timezone is set to UTC. I verified this by running `SHOW timezone;` in the psql shell, which returned `UTC`. I’m not sure if I’m missing anything in the way Sequelize or PostgreSQL are handling these dates. Could anyone help clarify what might be going wrong? Am I perhaps misunderstanding how Sequelize manages timezones when using PostgreSQL? Any insights into fixing this scenario would be greatly appreciated! This is part of a larger mobile app I'm building. What are your experiences with this? Is there a simpler solution I'm overlooking?
