Does the timer keep running if my computer goes to sleep?
The countdown is calculated from the real clock time. If your device sleeps, the display jumps to the correct remaining time when it wakes up. The alarm itself can only play while the device is awake, so for long timers keep it plugged in and disable sleep mode. If you reload the page, FinalTimer offers to resume the running timer.
