About the 42 Minute Timer
A 42 minute timer built for long blocks: accurate from an absolute finish time, visible fullscreen across a room, quietly backed by rain or brown noise, and alarming at zero even from a background tab.
TimerHub calculates remaining time from an absolute finish timestamp, so missed browser callbacks do not create drift. Read the timing accuracy methodology and reproducible tests.
