The need for modern mobile solutions for mainframe data centers

Today most CIOs, CTOs and IT experts are aware of the impact of digital transformation (DX) on their respective businesses and IT organizations. Disruptive technologies like Big Data, business analytics, cloud (computing and storage), digital payment, and more recently the algorithmic economy and the Internet of Things (IoT), have and are making their impacts felt.

There have been 3 phases in the evolution of time synchronization on IBM Z.
