 For example, if we create an `ITimer` with a *due time* and *period* set to **1 second**, the `DateTimeOffset` returned from `GetUtcNow()` during the timer callback may be different depending on the amount passed to `Advance()` (or `SetUtcNow()`).
 
-If we call `Advance(TimeSpan.FromSeconds(1))` three times, effectively moving time forward by three seconds, the timer callback will be invoked once at times `00:01`, `00:02`, and `00:03`, as illustrated in the drawing below. Both `FakeTimeProvider` and `ManualTimeProvider` behaves like this:

 Technically, both implementations are correct since the `ITimer` abstractions only promise to invoke the callback timer *on or after the due time/period has elapsed*, never before.
 
-However, I strongly prefer the `ManualTimeProvider` approach since it behaves consistently independent of how time is moved forward. It seems much more in the spirit of how a deterministic time provider should behave and avoids users being surprised when writing tests. I imagine users may get stuck for a while trying to debug why the time reported by `GetUtcNow()` is not set as expected due to the subtle difference in behavior of `FakeTimeProvider`.

-That said, it can be useful to test that your code behaves correctly if a timer isn't allocated processor time immidiately when it's callback should fire, and for that, `ManualTimeProvider` includes a different method, `Jump`.

 ### Jumping to a point in time
 
-A real `ITimer`'s callback may not be allocated processor time and be able to fire at the moment it has been scheduled, e.g. if the processor is busy doing other things. The callback will eventaully fire (unless the timer is disposed).

-To support testing this scenario, `ManualtTimeProvider` includes a method that will jump time to a specific point, and then invoke all scheduled timer callbacks between the start and end of the jump. This behavior is similar to how `FakeTimeProvider`s `Advance` method works, as described in the previous sectoin.
