The article considers the problematics of the reflection of time factor in the accounting methodology, making it possible to qualify and assess the facts of business life of companies in a certain way and form their financial reporting. The subject of time in accounting methods is discussed in the light of the provisions by G.H. Mead (1863-1931) and J.P. Sartre (1905-1980). The article also considers some provisions by Ya.V. Sokolov (1938-2010). The concerned example of the time factor influence on the accounting methods can be considered as one of the evidence that the accounting practices, formed by certain political, economic, social and other conditions, and controlled by a set of laws and regulations and/or professional standards, inherently can’t be the field of realization of some coherent and logically consistent theoretical construction.
