Timelapse Clock

What

A clock service that shows accurate time when the device clock is off. Synchronizes using server time with RTT-based offset correction — 3 samples, median selection. Supports fullscreen mode, burn-in prevention, screen wake lock, and color/font customization. Auto-resyncs every 30 minutes and immediately corrects when returning from a background tab.
