What does it guarantee?
Does it guarantee to block at least defined time?
Or it can unblock earlier than defined time?

In my app Timers.Timer.Interval = 1 takes much more longer than Thread.Sleep(1).
Why?

The problem is in the discrimination of the timer: which is dependent on your hardware and the OS. Have a look at the "Remarks" section of MSDN: Sleep function[^]

Low intervals (like 1ms) will always be less accurate than higher values.
