var kinfo = kinfo_proc()
var size = MemoryLayout<kinfo_proc>.stride
var mib : [Int32] = [CTL_KERN, KERN_PROC, KERN_PROC_PID, getpid()]
sysctl(&mib, u_int(mib.count), &kinfo, &size, nil, 0)
let start_time = kinfo.kp_proc.p_starttime
var time : timeval = timeval(tv_sec: 0, tv_usec: 0)
gettimeofday(&time, nil)
let currentTimeMilliseconds = Double(Int64(time.tv_sec) * 1000) + Double(time.tv_usec) / 1000.0
