Accurate and reliable knowledge of time is fundamental to cyber-physical systems for sensing, control, performance, and energy efficient integration of computing and communications. This statement underlies the proposal. Emerging CPS applications depend on precise knowledge of time to infer location and control communication. There is a diversity of semantics used to describe time, and quality of time varies as we move up and down the system stack. System designs tend to overcompensate for these uncertainties and the result is systems that may be over designed, inefficient, and fragile.The intellectual merit derives from the new and fundamental concept of time and the holistic measure of quality of time (QoT) that captures metrics including resolution, accuracy, and stability. The proposal builds a system stack ("ROSELINE") that enables new ways for clock hardware, operating system, network services, and applications to learn, maintain and exchange information about time, influence component behavior, and robustly adapt to dynamic QoT requirements, as well as to benign and adversarial changes in operating conditions. Application areas that will benefit from Quality of Time will include: smart grad, networked and coordinated control of aerospace systems, underwater sensing, and industrial automation.The broader impact of the proposal is due to the foundational nature of the work which builds a robust and tunable quality of time that can be applied across a broad spectrum of applications that pervade modern life. The proposal will also provide valuable opportunities to integrate research and education in graduate, undergraduate, and K-12 classrooms. There will be extensive outreach through publications, open sourcing of software, and participation in activities such as the Los Angeles Computing Circle for pre-college students.

准确和可靠的时间知识是用于传感，控制，性能和计算和通信能源有效整合的网络物理系统的基础。该声明是该提案的基础。新兴的CPS应用程序取决于推断位置和控制通信的时间的精确知识。在系统堆栈上下移动时，有多种语义来描述时间，时间质量也有所不同。系统设计倾向于对这些不确定性进行过度补偿，结果是可能设计过度，效率低下和脆弱的系统。智力优点源自时间的新概念和时间质量的整体度量（QOT），捕获包括解决方案，准确性和稳定性在内的指标。该提案构建了一个系统堆栈（“ Roseline”），可为时钟硬件，操作系统，网络服务和应用程序提供新的方式，以学习，维护和交换有关时间，影响组件行为的信息，并牢固地适应动态QOT的需求，以及在操作条件下的良性和对抗性变化。将从时间质量中受益的应用领域将包括：智能毕业，网络和协调的航空航天系统，水下感应和工业自动化。该提案的更广泛的影响是由于工作的基本性质造成的，这些性质构成了可以在现代生活的广泛应用的范围内应用的稳健且可调的时间质量。该提案还将提供宝贵的机会，以整合研究生，本科和K-12教室的研究和教育。通过出版物，软件的开放采购以及参加诸如大学前学生的洛杉矶计算圈等活动，将进行广泛的外展活动。
