Limits and behavior
Timing uses the browser’s monotonic clock and recalculates from absolute elapsed time. Refreshing the page resets both clocks.
FAQ
Will a busy tab make the timer drift?
The display may update less often in a background tab, but the remaining time is recalculated from the monotonic clock when it updates.
