Sigelith - @beat clock by Adam Koch

Sigelith — @beat clock shows universal @beat time right in your toolbar.

• Live @beat in the toolbar badge — 1000 beats a day, anchored to UTC: the same moment everywhere, no timezones
• Popup with a centibeat clock (@523.45) and the UTC time
• Two-way converter: local time ↔ @beat
• Works offline: time is computed locally; the extension only asks sigelith.org now and then to correct clock drift
• No tracking, no analytics, no account

@beat time splits the day into 1000 beats of 86.4 seconds. Midnight UTC is @000, noon is @500. More at https://sigelith.org/
