Hi, has anyone tried getting system uptime on iOS using KMM? I'm using SystemClock.elapsedRealtime() for Android. https://developer.apple.com/documentation/foundation/nsprocessinfo/1414553-systemuptime?language=objc - this API only returns the active time. I found some objective C and Swift snippets for getting the total uptime but I can't get them to work in Kotlin

In the end, I used Koin and an interface to use a native iOS code:

class SystemInfoImpl: SystemInfo {
func getDeviceUptime() -> Int64 {
var uptime = timespec()
if clock_gettime(CLOCK_MONOTONIC_RAW, &uptime) == 0 {
return Int64(uptime.tv_sec) * 1000 + Int64(uptime.tv_nsec / 1000000)
}
return -1
}
}

You can always bridge to the platform native API, that's the strength of KMP but wonder if org.jetbrains.kotlinx:kotlinx-datetime works for you?

Hi Pablichenko. I've checked the docs for datetime but haven't seen any references to system uptime or boot timestamp.

Ah I see, I initially thought you wanted to measure just time elapsed. But not specifically system uptime. Actually I thought this was possible too but doesn't seem to be the case 😕
