Chronos is a professional-grade timekeeping instrument that visualizes the physical, symbolic, and biological rhythms of our existence. Synchronized against Stratum 1 NIST sources with sub-second precision, it goes beyond simple device time to bridge atomic accuracy with global existential reality.
CORE DOMAINS:
1. PHYSICAL TIME
- Atomic Clock: Stratum 1 NIST sync with RTT compensation, IQR outlier rejection, and slew-based drift correction. Displays UTC, TAI time with leap seconds (+37s), and Unix epoch milliseconds. Tap to copy ISO 8601 timestamp.
- Clock Drift: Real-time device vs NIST offset comparison with drift rate in Ξs/s.
- Pulsar Clock: Simulated high-frequency signal based on PSR B1919+21.
2. SYMBOLIC TIME
- Doomsday Clock: Humanity's proximity to global catastrophe (Bulletin of the Atomic Scientists).
- Carbon Budget: Remaining CO2 budget for 1.5°C ticking down in real time at 1,167 tonnes per second.
- Biodiversity Loss: Species extinction counter tracking ~150 species lost per day at 1,000Ã background rate.
3. BIOLOGICAL TIME
- Circadian Rhythm: Phase-based wake/sleep visualization with user-configurable hours.
- Heartbeats Remaining: Real-time countdown based on your age and heart rate.
- Evolutionary Time: Solar evolution and biological deep-time cycles.
TECHNICAL FEATURES:
- 60 FPS update loop with battery-aware power management.
- NTP-grade sync with confidence scoring and RTT transparency.
- All user settings persisted across sessions.
- OLED-friendly dark design to prevent screen burn-in.
Chronos is not a watch. It is a dashboard for the temporal reality of the 21st century.
