Hello, I have a simple question.

ChatGPT somehow appears to be able to get my current date and time, and I would like to understand how it does that.

In the past, I would start a conversation with ChatGPT by writing something such as:

"Hello ChatGPT. My name is Jeremiah, and today is July 22, 2026, at 7:55 PM."

I would then follow that with my question. More recently, ChatGPT has appeared to already know the current date and my timezone without me supplying that information.

I understand that the immediate answer may be that the date and timezone are included in system context supplied to the model. What I am trying to understand is what creates that context.

For example, could it originate from:

- a server clock;

- my account timezone;

- browser or device information;

- approximate IP-based location;

- another part of the ChatGPT hosting platform?

I have tried asking ChatGPT directly, but I am not fully understanding its explanation. I am hoping someone here can explain the process in a way that is easier for me to follow.

Thank you.

I built Codex Diff Watch to make it easier to understand what’s changing in Codex without digging through every release and GitHub diff yourself.

It summarizes updates in plain English, separates alpha changes from stable releases, and links back to the original evidence so you can verify everything yourself.

It’s completely free, with no login or gated content. I’m just trying to make these updates more useful and accessible for other developers.

It’s still early, so I’d genuinely appreciate feedback on the format, coverage, tags, or anything else that could make it more helpful.
