Excel converts a time such as 1:01:01 as hours:minutes:seconds to a number, but displays it how it was entered. When trying to add milliseconds, it gets bent out of shape. Milliseconds can be displayed if you try hard enough. I'm not an expert but never found a way of using that value in a calculation, though.
