Allow clocks to get their time from cellphones

[Metspitzer]

Could wall clocks and car clocks be built with a receiver that would
accept the current time from a cell phone?

Could the correct time be broadcast from the cellphone each time it is
used to allow devices with an internal clock to sync with them?

I see no reason why a cellphone could not continually transmit the
correct time. The extra circuitry would cost about 25 cents.

Anyone think this would be a practical idea?

As others have pointed out, there are better solutions technically. Then
there is the economic aspect. Do you really want to pay VZW $70/mo. to keep
your clock set? ;-)

What is was really shooting for are small items that don't necessarily
need "balls on" accurate time, but having the correct day and hour
would be useful without having to manually set them.

Stuff like answering machines, microwaves, coffee makers, portable
cameras or a wrist watches.

I would think it would be 0 cost for cellphones to send out the time
on a regular basis and anything needing the current time could be
modified to acquire the time for a very low cost.

I know there are other ways, but seems like a 0 cost way.

So why not WWVB, as is intended?

Cell companies don't give their services away, if you hadn't noticed.

The other ways are the zero cost ways. You're trying to make it expensive.

I don't know, but there are many things that don't use it.

My coffee pot and my microwave never have the correct time. Could
they get the time from WWVB? Yes? Do they? No

Would it be practical to use a small local signal coming from a
cellphone? Maybe.

What a moronic statement. Of course there are "things" that don't even have a
clock.

Do you have a point?

Practical, sure. Expensive, you bet your a$$. Why pay for cell service when
both WWVB and GPS are free?
