Recently, the definition of time has been introduced by introducing the irreversible thermodynamics into the analysis of the atomic irreversibility. In this way, time is defined by means of the entropy generation and the entropy rate. But, which clock can be used to measure this time? In this paper a thermodynamic clock is designed by using the properties of a black body. So, a relation between the definition of time by entropy and a measure of temperature of a black body has been obtained. The result obtained agree with the Relativity and the thermal time hypothesis, obtaining a link between quantum mechanics, relativity and thermodynamics, by the irreversible thermodynamic clock operational approach.
