Is it possible to allow the runner to input milliseconds into the time field but only have full seconds visible on the leader board.

no.

also why would you want to track the milliseconds if you dont want to show them on the boards?

@SioN you might want to have milliseconds to prevent ties and make ranking more accurate but also make the leaderboard more concise

@retrozy yes thats the point of milliseconds, but i was confused why the op would want them to not be visible even if they were internally there

you could say it looks cleaner without​ ms

@retrozy but the op doesnt want to see the ms.

Typo

If you don't like how the milliseconds look, you can choose between "9h 59m 59s 999ms" and "9:59:59.999". This only appears for your account.

This can setting be changed in your settings under Appearance
