Time Anchor for ChatGPT

Adds the current local date, time, and time zone to ChatGPT prompts before sending.

Time Anchor for ChatGPT adds the current local date, time, and time zone to your ChatGPT prompts before sending. This helps give ChatGPT clearer time context when your prompt depends on today, yesterday, tomorrow, schedules, daily work, audits, planning, or follow-up conversations. It can also help ChatGPT better understand how much time has passed when you return to an older conversation. Features: * Adds a timestamp to ChatGPT prompts before sending * Supports top or bottom timestamp placement * Optional seconds in the timestamp * Uses your browser/system clock * Works on chatgpt.com and chat.openai.com * Runs locally in your browser * Does not contact external services * Does not collect, transmit, sell, or share user data Example timestamp: [Time Anchor: Now = Monday, June 15, 2026 at 11:30 AM CDT. You must use this as the current time for this message. Silently compare it to the previous Time Anchor timestamp for elapsed time. Use this for all relative dates and times.] Note: Timestamps are only added when the prompt box contains typed text. File-only uploads without typed prompt text are left unchanged to avoid creating accidental timestamp-only prompts. Privacy: Time Anchor for ChatGPT stores only local extension preferences, such as enabled/disabled state, timestamp placement, and whether seconds are included. These settings are not transmitted off your device. Disclaimer: Time Anchor for ChatGPT is an independent browser extension and is not affiliated with OpenAI. ChatGPT is a trademark of OpenAI.
