Techniques for clock manager monitoring for time sensitive networks are described. An apparatus, comprises a clock circuitry to manage a clock for a device, a processing circuitry coupled to the clock circuitry, the processing circuitry to execute instructions to perform operations for a clock manager, the clock manager to receive messages with time information for a network and generate clock manager control information to adjust the clock to a network time for the network, and a detector coupled to the processing circuitry and the clock circuitry, the detector to receive the clock manager control information, generate model control information based on a clock model, compare the clock manager control information with the model control information to generate difference information, and determine whether to generate an alert based on the difference information. Other embodiments are described and claimed.
