Issue Description:

I am trying to get the elapsed nanosecods via the Calendar API like this

let elapsedNano = Calendar.current.dateComponents([.nanosecond], from: self.startTime, to: now).nanosecond

This fails on Ubuntu 18.04 with the following error

Fatal error: : file Foundation/NSCalendar.swift, line 617

Using .second in the given call seems to work. The same code on MacOS works fine.

This was fixed in swift-5.0 to return the correct nanosecond component

$ cat sr-9439.swift
import Foundation

let now = Date()
let then = Date(timeIntervalSince1970: now.timeIntervalSince1970 - 1.2345678)
let elapsedNano = Calendar.current.dateComponents([.nanosecond], from: then, to: now).nanosecond
print(elapsedNano ?? "nil")

$ ~/swift-5.0.3-RELEASE-ubuntu14.04/usr/bin/swift sr-9439.swift
