My app has a lot of "clock" counters that show progress. To wit, someone shared this code with me a while back:

@Composable
fun currentTimeAsState(
    updateInterval: Duration = 1.seconds,
    clock: Clock = Clock.System,
): State<Instant> {
    return produceState(initialValue = clock.now()) {
       while (isActive) {
          delay(updateInterval)
          value = clock.now()
       }
    }
}

It's been great. I admit, I don't entirely understand how this part of Compose works.

I notice though, that if I have a screen full of many widgets that are "counting", that they seem to update independently. I assume this is because I'm creating many different TimeAsState things/objects/routines? and they're all running independently. I'd like the updates to be more synchronized throughout the app. Does it make sense to do wrap this with a CompositionLocalProvider thing, and then just have one clock as state avaiable to everyone? Or is there a better way to reduce the number as well as get some synhronization?

All the usual debate about passing state directly vs via CompositionLocals applies

But otherwise, yea makes sense to have a single time source somewhere that is shared

i recommend using molecule Library made by Cash up

It’s a great library, but I don’t see what it has to do with this question
