In other news, a sweeping Internet virus has caused all Ethernet-connected clocks to be set back 4 hours. Consequently, the IT departments of several Fortune 500 companies showed up late today.

It only gets it's power from the Ethernet if you have PoE, which most "small businesses or houses with cathedral-sized rooms" don't have so they have to use the AC adapter.

"what about the clocks we have mounted on the wall "

They have been making clocks that get their time sync from an AM signal for decades.

RIGHT you are!!! Just google: atomic wall clock
These "atomic clocks" however they are not atomic but sync with the many actual atomic clocks around the world that are sending out radio signals that are picked up by an appropriate receiver.
http://en.wikipedia.org/wiki/Atomic_clock#Radio_clocks

So begs to ask, why an Ethernet wall clock? It's not a simplier, less expensive, less power, or even more elegant mouse trap than the radio clock. Even if they come out with a wireless ver as in WiFi or what ever.... Isn't that just a me too (ie: radio vs WiFi) that will most likely use more power, etc. So why??? There are also GPS clock devices that can be deployed for even more accuracy than the radio "better brands of radio clocks are normally accurate to the second" but GPS clocks can be even more accurate. SO only if mounting an radio or GPS antenna (even a remote antenna) is not possible does a Ethernet clock make sense.

with this technology, they could make router(or modem)/alarm clock/ radios. with the time syncing, that would get me interested

wow, looks awesome! NOT... lame idea, any digital clock will run for years and with a great amount of accuracy.
