The article identifies the problem of determining time in various sciences, presents a physical interpretation of time and proves that the method and means of measuring time are due to a real physical periodic process. The means of measuring time are considered in historical retrospect. Data on the measurement of time using a homemade equatorial-type sundial and the assessment of their errors are presented.
