Timestamps

ChatGPT hover message timestamp

Updated June 1, 2026

Quick answer

ChatGPT does not show message send times when you hover over replies. The platform records this data internally, but the interface hides it. GPT Master fixes this by displaying an inline timestamp above every message automatically. Hovering over this timestamp then reveals an expanded tooltip with the full date and day of the week.

Many modern messaging tools like Slack or Discord reveal message send times when you glide your cursor over a message. If you expect the same behavior on chatgpt.com, you will find that hovering does nothing. ChatGPT leaves the interface completely empty of time markers. You do not have to copy text or export history to find these dates. A browser extension can solve this by putting always-on inline times directly in your view.

Frequently asked questions

Can I see timestamps by hovering in the official ChatGPT mobile app?
No. Hovering is a desktop-only concept, and the native ChatGPT mobile apps on iOS and Android do not surface message-level timestamps. GPT Master is a desktop browser extension.
Does the hover tooltip show my local time or UTC?
The inline timestamps and their hover tooltips are shown in your local system time zone, automatically matching your browser settings.
Does hovering over messages send data to external servers?
Never. The timestamp data is retrieved entirely from ChatGPT's existing local API response inside your browser. No message content or timing details are sent outward.
