This book, written in Swedish the same year Einstein received the Nobel Prize for the Photoelectric Effect, contains much of the material in Nordenson's expanded English book, Relativity, Time and Reality, published forty-seven years later. It presents a very detailed analysis of how Einstein used (or abused) the concept of time. Einstein's use of different concepts of time without real definitions and relations to reality means, according to Nordenson, that his theories are inconsistent and not real theories. A copy is available from Stockholm University Library.
