English text:How Apple synchronized all your Apple Watches Here's
This year's new year countdown time, have you ever had this experience? TV excitedly count down the final five seconds, you may have found your TV cabinet in the VCR time seems to slow a minute. Who knows exactly where the end of 2015 is in the world? Lynch Kevin, vice president of technology will tell you Watch Apple know.
"People who have Watch Apple are absolutely the most accurate people in the time when they are down. "Lynch says.". As everyone knows, the vice president of technology is the sales of up to $1 billion Apple Watch the number one hero. Watch Apple is not only very precise, and each piece of Watch Apple time is exactly the same. If you put two pieces of Apple Watch put together, you will find that even their second swing are exactly the same.
Such accuracy is not a coincidence. Lynch explains the profound principle to us, from the complex relationship between the universe and the arm wearable technology.
For the accuracy of the worry is not just a spring clock; digital system also has a clock deviation problem. This system should be fully synchronous, at the same time send all signals, but inevitably occurs when the transmitted signal has time difference. Only a solution to the problem of the approach is to reduce the number of signal transmission, the signals of all time are delivered to a central server to send.
Apple just did it.
"First of all, we set up and manage our NTP network timing devices around the world. "Lynch said. He told us that apple in the global total 15 stratum 1 first order NTP network school when (after class of atomic clock). Placed the satellite antenna are installed on the roof of the these NTP building, to GPS satellite communications to obtain time information; the information from the United States Naval Observatory. In other words, the satellites receive signals from the same system.
The server and then through the network to the world of the iPhone on the transmit signal, and the iPhone and via Bluetooth and apple watch contact up. Of course, this process also generates time error. "We're going to have to adjust the time delay in the communication process. "Lynch explains.
Apple also Apple Watch designed a very accurate timer, table used in temperature control of crystal oscillating body. The task of the shock body is to ensure that the time precision of the watch at extreme temperatures. Lynch said: "as a hardware product, Apple Watch time accuracy than iPhone do. Rigorous, is four times more accurate than the iPhone.
"We have a lot of time to ensure the accuracy of the time. Apple even shoot Apple watch with a high speed camera, frame by frame to check the second hand to walk, in order to test the its accuracy. "Lynch said.
"Apple has repeatedly stressed that the apple watch time accuracy is how amazing, but users will generally connect the smart watches to mobile phones, watches can be via mobile phone to receive time information and iPhone clock itself is based on GPS signal or network set. So I don't think there is much innovation. "Watch Blogto, the chief editor and watch expert, Adams Ariel, is a comment.
Suggests Adams atomic clock chip size of many Bathys, Hoptroff and other foreign watches are built-in, who is the world's most accurate electronic table. Overall, Adams believes that the time precision of Watch Apple is actually the same as that of iPhone.
But Adams himself is a apple watch fans, he told us that although every year there are numerous brands invited him to wear their own watch. "I couldn't think of a 2015 with which watch can also than apple watch makes me more stunning. Watch Apple is definitely my heart big love. "
Unless you have a lot of Apple watch and a atomic clock, the time accuracy "in fact, it does not make much sense, anyway, it is impossible to prove. But if Lynch and apple is right, at least that this year's global Apple watch in 2016 first second ring out at the same time the.
