Timer — Countdown and Count-Up for Games
Remaining01:00
Countdown for a turn limit, count up for how long the round actually took. Either way the clock is computed from a fixed end time rather than ticked down step by step, so locking the phone or switching tabs does not cost you the seconds you were away.
Turn limits without a sand timer
Thirty seconds is the usual limit in word and drawing games, and a minute is about right for anything where people need to think. Set it once and the same length is there next time — the last duration is remembered in this browser.
Why it does not drift
A timer that subtracts one second from a counter every second is wrong by a little on every tick and stops dead when the tab is suspended. This one stores the moment it should finish and works out the difference each time it draws, which is why it is still correct after two minutes in your pocket.
