[Internet Society Blogs] Time Synchronization, Security, and Trust

Time is something that is often overlooked or taken for granted, but the accuracy and reliability of time is critical to our lives and must be protected. Time is a core concept underlying nearly all physical and virtual systems. Distributed computer systems, key to many functions inherent in our daily lives, rely on accurate and reliable time, yet we rarely stop and think about how that time is constructed and represented. Accurate and reliable time is needed to determine when an event occurs, in what order a particular sequence of events occurs, or when to schedule an event that is to occur at a particular time in the future.
