TimeKeeper by TheAnarchoX

TimeKeeper adds inline timezone conversions to articles, live blogs, schedules, event pages, and other webpages so you do not have to manually calculate what a posted time means for you.

When TimeKeeper finds a time mention, it looks for nearby context such as timezone abbreviations, city names, article metadata, page titles, schedule notes, and phrases like “local time” or “all times Eastern.” If it can determine that the source time is different from your configured timezone, it adds a compact inline conversion directly next to the original time.

TimeKeeper is useful for reading global news, following live blogs, tracking product launches, checking sports or conference schedules, and coordinating across regions. It supports common formats like 9am PT, 12pET, 11.20am BST, 14:48:37 UTC, UTC offsets, and full date/time strings.

- Converts detected page times into your local or selected timezone

Privacy:
TimeKeeper scans page text locally in your browser to identify time mentions and timezone context. It does not send page content, browsing history, or detected times to any server. Your preferences are stored using Chrome storage.
