RxNet TestScheduler and Windowing not doing what I expected - system.reactive

Question

I have been trying to learn ReactiveUI + RxNet lately... I love them both and they are quite mind bending... I have been reading 'Programming Reactive Extensions and Linq' and it includes this code snippet (modified so that it uses the latest classes/methods):
var sched = new TestScheduler();
var input = sched.CreateColdObservable(
OnNext(205, 1),
OnNext(305, 10),
OnNext(405, 100),
OnNext(505, 1000),
OnNext(605, 10000),
OnCompleted<int>(1100));
int i = 0;
var windows = input.Window(
Observable.Timer(TimeSpan.Zero, TimeSpan.FromMilliseconds(100), sched).Take(7),
x => Observable.Timer(TimeSpan.FromMilliseconds(50), sched));
windows.Timestamp(sched)
.Subscribe(obs =>
{
int current = ++i;
Console.WriteLine($"Started Obserable {current} at {obs.Timestamp.Millisecond:n0}ms");
obs.Value.Subscribe(
item =>
Console.WriteLine($" {item} at {sched.Now.Millisecond:n0}ms"),
() => Console.WriteLine($"Ended Obserable {current} at {sched.Now.Millisecond:n0}"));
});
sched.Start();
This is the ouput:
Started Obserable 1 at 0ms
1 at 0ms
10 at 0ms
100 at 0ms
1000 at 0ms
10000 at 0ms
Ended Obserable 1 at 50
Started Obserable 2 at 100ms
Ended Obserable 2 at 150
Started Obserable 3 at 200ms
Ended Obserable 3 at 250
Started Obserable 4 at 300ms
Ended Obserable 4 at 350
Started Obserable 5 at 400ms
Ended Obserable 5 at 450
Started Obserable 6 at 500ms
Ended Obserable 6 at 550
Started Obserable 7 at 600ms
Ended Obserable 7 at 650
And this is the expected output:
Started Observable 1 at 0ms
Ended Observable 1 at 50ms
Started Observable 2 at 100ms
Ended Observable 2 at 150ms
Started Observable 3 at 200ms
1 at 205ms
Ended Observable 3 at 250ms
Started Observable 4 at 300ms
10 at 305ms
Ended Observable 4 at 350ms
Started Observable 5 at 400ms
100 at 405ms
Ended Observable 5 at 450ms
Started Observable 6 at 500ms
1000 at 505ms
Ended Observable 6 at 550ms
Started Observable 7 at 600ms
10000 at 605ms
Ended Observable 7 at 650ms
Any idea why? what have I missed?

I don't know what you have in your OnNext method, but the constructor for Recorded<Notification<T>>, what is what you put into the CreateColdObservable method, takes ticks and not milliseconds as the first argument. So I would try this:
var input = sched.CreateColdObservable(
OnNext(2050000, 1),
OnNext(3050000, 10),
OnNext(4050000, 100),
OnNext(5050000, 1000),
OnNext(6050000, 10000),
OnCompleted<int>(11000000));
