  With the advancement of technologies like Industry 4.0, communication
networks must meet stringent requirements of applications demanding
deterministic and bounded latencies. The problem is further compounded by the
need to periodically synchronize network devices to a common time reference to
address clock drifts. Existing solutions often simplify the problem by assuming
either perfect synchronization or a worst-case error. Additionally, these
approaches delay the scheduling process in network devices until the scheduled
frame is guaranteed to have arrived in the device queue, inducing additional
delays to the stream. A novel approach that completely avoids queuing delays is
proposed, enabling it to meet even the strictest deadline requirement.
Furthermore, both approaches can be enhanced by incorporating network-derived
time-synchronization information. This is not only convenient for meeting
deadline requirements but also improves bandwidth efficiency.
