@Herschel Are you like suggesting every place where durations are used should be switched out to durations? [Example](https://github.com/ruffle-rs/ruffle/blob/a320e3b1d0d4f271aa1f079574a969873e5967aa/core/src/player.rs#L563) Or more like all functions' input and return types should be `std::time::Duration`....

Ah my bad on not giving the other defs
