Class, Structure, Enumeration

public struct TimeSpecification: Comparable,
                                 ExpressibleByIntegerLiteral,
                                 ExpressibleByFloatLiteral {
  public var seconds:Int64 = 0
  public var nanoseconds:Int32 = 0
  /* ... */
}
public enum Clock {
  case Calendar
  case System
  
  public func timeSpecification() -> TimeSpecification? {
    /* ... */
  }
}

How to use

Build and install:
./build-install.rb --install-prefix=/path/to/your/system --install
Then, you can use it in your project:
swiftc ./your/project/main.swift -I/path/to/your/system/include -L/path/to/your/system/lib -lSwiftTimeSpecification

Sample Code

import TimeSpecification
let start = Clock.System.timeSpecification()
// your code
let end = Clock.System.timeSpecification()

if start != nil && end != nil {
  let duration = end! - start!
  // For example, duration == TimeSpecification(seconds:0, nanoseconds:100)
  print("\(duration)") 
}
