       let dateFormatter = DateFormatter()
       dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
       let dateold = dateFormatter.date(from: timestamp)!
       let datenew = dateFormatter.date(from: last_timestamp)!

       let calendar1 = Calendar.current
       let components = calendar1.dateComponents([.year,.month,.day,.hour,.minute,.second], from:  dateold, to:   datenew)

You said you want the hours, minutes and seconds between the two dates, yet you are only getting the seconds components. The two dates are exactly 54 minutes and 0 seconds apart, so that's why you got 0.

You should only pass .hour, .minute, .second, and print all three components:

let components = calendar1.dateComponents([.hour,.minute,.second], from:  dateold, to:   datenew)
print(components.hour!)
print(components.minute!)
print(components.second!)

Or, use a DateCompoenentFormatter which formats the components for you:

let componentsFormatter = DateComponentsFormatter()
print("Idle time: \(componentsFormatter.string(from: components)!)")
