Synchronization is maintained among a plurality of network devices (102,...) having local clocks. A first packet including global time reference (606) derived from local clock is broadcast from a first network device to other devices. The clocks of the network devices are adjusted. The difference between a free running clock and a first network global time reference is determined (610). A first network offset is calculated (612). Similarly a , second network offset is calculated to account for the difference between the free running clock and the second network global time reference.

Why it's free to use
- Filed March 7, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 7, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 7, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
