    • elapsedMillisSince

      @Deprecated public static long elapsedMillisSince(long start)
      Deprecated.
      Utility method to provide the elapsed time using milliseconds since epoch. This serves as an alternative for the former constructor based on a Date argument. This should be used only when converting old code that relies on that constructor as it can provide incorrect measurements in rare circumstances
      Parameters:
      start - the timestamp in milliseconds since epoch
      Returns:
      the elapsed time in milliseconds
