What it does

ChatGPT can lose track of exact timing in long-running conversations. Time Anchor adds a clear timestamp line to prompts so “today,” “yesterday,” “tomorrow,” daily logs, audits, and follow-ups have better context. It can also help ChatGPT recognize how much time has passed when you return to an older conversation.

Automatic timestamp Adds current local date, time, and time zone before sending prompts.
Simple controls Turn timestamps on or off, choose placement, and optionally include seconds.
Focused access Designed only for chatgpt.com and chat.openai.com.
