Apple’s Kevin Lynch Explains Method Behind Apple Watch’s Precise Timekeeping

One of the Apple Watch features Apple often highlights is the device’s precise timekeeping, which Apple says is within 50 milliseconds of the global time standard. Apple’s VP of Technology, Kevin Lynch, today spoke with Mashable and The Telegraph to share some details on how Apple achieves that level of accuracy.

Lynch told Mashable that the Apple Watch is so accurate that the hands of two Apple Watches placed next to one another will move in perfect unison. This is achieved primarily through 15 Network Time Protocol (NTP) servers that Apple has around the world, kept inside of buildings with GPS antennas that connect to GPS satellites broadcasting time data from the U.S. Naval Observatory in Washington, D.C. The Observatory houses an ultra accurate atomic clock, which uses electronic transition frequency to measure time.

Apple’s time servers communicate the time to iPhones across the world, and the iPhone in turn syncs with the Apple Watch via Bluetooth to provide the exact time. Communicating a GPS signal from a server to an iPhone to an Apple Watch over Bluetooth has its own delays, which Apple corrects for via software. Apple’s NTP servers make sure iPhones and Apple Watches keep time at „Stratum One“ accuracy, within milliseconds of „Stratum Zero“ devices.

Speaking to The Telegraph, Lynch also described the hardware inside of the Apple Watch that makes sure the time remains accurate. Each Apple Watch has a temperature-controlled crystal oscillator inside to combat time drift that clocks and watches see. The oscillator also makes sure the Apple Watch remains warm enough to keep accurate time in very cold climates. Thanks to this hardware, the Apple Watch is even more accurate than the iPhone.

„The second hand on every Apple Watch is perfectly in sync, and each device is accurate to 50 milliseconds of Co-ordinated Universal Time (UTC), the world’s time standard, which is below human perception, so when you look at it you can’t tell the difference,“ he explains.

With New Year’s Eve approaching, Lynch says Apple Watch owners will have the most accurate watches in the room. „If you’re in a room on New Year’s Eve wearing one, you will be the best reference for when the New Year actually begins,“ he said.

Adobe Unveils Photoshop and Premiere Elements 14 for Mac

Adobe today released new versions of Photoshop Elements and Premiere Elements, its lower-cost photo and video editing software aimed at consumers. In this year’s update, both Photoshop Elements 14 and Premiere Elements 14 have gained several new features and refinements to existing tools, making it easier than ever to use Adobe’s software for improving photos and videos.

Photoshop Elements 14, Adobe’s image editing software, has gained tools for removing camera shake and for removing haze. Adobe first introduced haze removing tools with its 2015 Creative Cloud update, and has now brought that capability to Photoshop Elements 14. While the haze removal tool is useful for improving the look of outdoor shots, it can also be used to clean up old photos and improve the lighting in backlit shots.

Adobe’s shake removing tool introduces auto shake reduction. It’s able to analyze a photo and fix it to remove blur caused by camera movement, with tools for fine tuning the final look of the image.

In addition to these two new tools, Adobe has also included new capabilities for several existing features. Guided Edits, the built-in tutorial tool in Photoshop Elements has been updated with new options that walk customers through adding motion blur and resizing photos to specific frame sizes. Guided Edits also include new before and after effects to make it clearer what each one does.

There are enhanced auto correct tools that provide five correction options after subject, color, composition, and lighting for each image have been analyzed, and there are much improved tools for selecting fine details in like hair and pet fur in a photo.

Facial recognition capabilities have been improved and faces are now recognized faster and more accurately, and there’s a map that shows where photos with GPS included were taken.

Premiere Elements 14, Adobe’s video editing software, now includes support for importing and editing 4K video from a range of different cameras, which is this year’s biggest addition. As with Photoshop Elements 14, Premiere Elements 14 has gained improved Guided Edits for adding dramatic effects to videos.

Audio enhancement tools have been moved front and center in the app, making them more accessible, and motion titles have also been improved. It’s easier to manage video clips with improved organizational tools and better facial recognition to sort by people, place, and event, and both photos and videos with GPS information embedded will be displayed on a map.

Both Photoshop Elements 14 and Premiere Elements 14 for Mac and Windows can be purchased from Adobe’s website for $99.99 each. Bundles are available for $149.99, and existing users can upgrade for $79.99 for one product for $119 for the bundle.
