TLDR
The basic concepts of the special and general theories of relativity are described in this article, and simple examples are given to illustrate the effect of relativity on measurements of time and frequency in the near-earth environment.Abstract:

Synchronization and relativity
TL;DR: The use of concepts and formulas of the special and of the general theory of relativity has become a necessity in electronic systems that use high precision timing, especially space systems as mentioned in this paper, particularly as they apply to time coordination.

Time Scales for Theory and Practice
TL;DR: Very early human experience has suggested a practical definition for the measurement of time: we define a unit of time by defining a standard (cyclical) process, and whenever this process completes its cycle identically, a unit has elapsed as mentioned in this paper.

Reference systems: What are they & what’s the problem?
TL;DR: At the very beginning of the work of the WGRS Sub-Groups on Frames and Origins and on Time, it became clear the the primary mission of the SGFO and SGT was to jointly prepare general recommendations on space-time references on which they could base their specific recommendations.
