Abstract:
Methods, apparatuses, and computer program products for synchronizing time across a plurality of devices connected to a network are provided. Embodiments include detecting, by a particular device, a synchronization initiation event; in response to detecting the synchronization initiation event, broadcasting, by the particular device to each device of the plurality of devices, a synchronization request; receiving, by the particular device, a plurality of time acknowledgments from the plurality of devices, each time acknowledgement indicating a current time of a device and a device initialization time indicating a time that the device last set the current time of the device; selecting, from the plurality of time acknowledgements the time acknowledgement with the shortest duration between an indicated device initialization time and an indicated current time of a device; and setting a current time of the particular device based on the current time indicated in the selected time acknowledgment.
