All clocks are necessarily irreversible and thus subject to uncertainty. In the classical case the uncertainty arises from thermal noise. In the quantum case the uncertainty arises from the nature of quantum measurement. I present  examples of quantum clocks and highlight the essential role played by measurement.  This leads to a physical implementation of the Rovelli-Connes thermal time hypothesis.
