Hey all, does anyone have a good suggestion on how to measure execution time and log the duration in a finally block?
Is this only achievable explicitly like the following?

val startTime = System.currentTimeMillis()
try {
    <some code>
} finally {
    val duration = Duration.ofMillis(System.currentTimeMillis() - startTime)
}

Thanks in advance ✌️

What about https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.time/measure-time.html?

If you want to keep the finally block you can simplify it a bit like this:

val start = TimeSource.Monotonic.markNow()
try {
  TODO("Some code")
} finally {
  println("Time taken: ${start.elapsedNow()}")
}

Or use the TimeSource directly:

val start = TimeSource.Monotonic.markNow()
        try {
            
        } finally {
            val duration = start.elapsedNow()
        }

Another possibility, though I prefer the more explicit try-finally suggestions above:

val (result, duration) = measureTimedValue {
    runCatching {
        ...
    }
}
println(duration)
println(result.getOrThrow())

Thanks guys! Will go with the Timesource approach!
