Hi everyone,

I would like to propose a feature for ChatGPT and Codex: Contextual Timestamps.

Currently, LLMs lack a real perception of time within a chat session. They treat the entire conversation as if it happened in a single moment, making it hard to reference previous prompts based on time.

How it would work:
Every time a user sends a prompt, the system should automatically inject the exact date/time and the time elapsed since the last message into the context (e.g., [Timestamp: 2026-08-08 13:00 UTC | Time elapsed: 15 minutes]).

Why this is useful:

  1. Time Awareness: Users could say “Update the code I asked for 10 minutes ago” or “Remind me about this in 3 hours”, and the model would know exactly what that means.
  2. Better Coding (Codex): It would help Codex handle version history, logs, and time-sensitive functions much more accurately during long coding sessions.
  3. Improved Workflows: It prevents the model from losing track of time in long, multi-day interactions.

What do you think? I believe this would greatly improve context management!
