It seemed like Microsoft had taken another step toward its pledge to be device-agnostic earlier this year, when it announced a feature that would let Windows 10 users pick up where they left off on iOS or Android devices, but we’re going to have to wait.
In response to a question from The Verge’s Tom Warren, Microsoft’s Joe Belfiore confirmed that Timeline will not be released with the Fall Creators Update of Windows, expected in September. Instead, it will ship in the next major release in March 2018.
Correct. Timeline won't be in the Fall Creators Update. We're planning for it to be in early insider builds shortly after FCU is out.

Belfiore showed off how Timeline worked at Microsoft’s Build developers conference in Seattle last May. It is supposed to work through the Cortana app on both mobile operating systems, allowing you to see a visual representation of your activity on a Windows PC from those devices and select the activity you’d like to resume on your phone.
It’s part of a series of features slated for upcoming releases that acknowledge how computing usage patterns have shifted over the years, while keeping a Windows PC at the heart of that experience. Microsoft is also planning to include a feature called Cloud Clipboard, which lets you cut, copy, and paste between different devices, and Project Rome, which extends many of these same features to third-party apps written by Windows developers, in future Windows releases.
