> Milliseconds are converted to seconds by dividing by 1000 and rounding down like so It seems like the simpler explanation is that the iPhone actually rounds to the closest integer rather than rounding down. (Whether they do this invisibly by adding 0.5s and rounding down is an implementation detail.)
That’s most likely what it does indeed, much more elegant than keeping track of the extra 500ms.
One of the main benefits is that it doesn’t require the internet and can synchronize iPhones, iPads, and Apple TV’s using either peer-to-peer WiFi or Bluetooth with no manual pairing.
Also had an interval timer for exercises, group activities, etc...

The sentence quoted is for the first example in the post, not the iPhone timer. That’s most likely what it does indeed, much more elegant than keeping track of the extra 500ms.
I get the feeling this pun wasn’t intentional, but it’s a good one nonetheless.
It's a good example of how measurement of time in terms of human perception differs from the pure mathematical sense, and rounding is a good compromise here (wherever it doesn't display fractional seconds).
