Question

I\'m working on a Android application and I need to parse a duration string of this form \"00:00:00.000\" (Ex: \"00:00:38.47\" or \"00:03:27.11\").

My final goal is

Answer 1

  val time = LocalTime.parse("00:01:08.83", DateTimeFormatter.ofPattern("HH:mm:ss.SS"))

  println(time.toSecondOfDay())
  println(time.toNanoOfDay())
  println(time.toNanoOfDay().toFloat() / 1_000_000_000)

Output:

68830000000
68.83
