1. An apparatus comprising:
at least one processing device comprising a processor coupled to a memory;
the at least one processing device being configured to perform steps of:
establishing a first connection to a specified network time source via a network-connected device that the at least one processing device is coupled to;
acquiring first timing information from the specified network time source via the network-connected device, the first timing information comprising a current time value and first accuracy information for the specified network time source;
setting an internal real-time clock of the at least one processing device based at least in part on the current time value included in the first timing information;
maintaining, subsequent to decoupling of the at least one processing device from the network-connected device, the internal real-time clock of the at least one processing device;
establishing a second connection to an endpoint device; and
providing, to the endpoint device, second timing information, the second timing information comprising a current time measurement of the internal real-time clock of the at least one processing device and second accuracy information for the internal real-time clock of the at least one processing device, the second accuracy information for the internal real-time clock of the at least one processing device being based at least in part on the first accuracy information for the specified network time source.
