Summary/Abstract: At every moment of time, a single context becomes real. Therefore, every moment splits the class of all contexts into two parts, the realized ones until that moment and the contexts that are not yet realized. The first part represents the past at a certain moment. A proposition is necessarily true at a given moment if it is a consequence of the past. From this definition of necessity it follows that the modal values of propositions depend on time, namely, the modal value of a proposition can be different at two given moments. For instance, there are propositions so that they are possibly true at a moment and become impossibly true later.
