Assuring Resilient Time Synchronization

2008 Symposium on Reliable Distributed Systems, 2008
In many distributed and pervasive systems the clocks of nodes are required to be synchronized to a unique global time. Due to unpredictable system and environment characteristics, the distance of a local clock from global time is a variable factor very hard to predict.

Synchronous electric time service

Electrical Engineering, 1932
PREVIOUS to 1916 no commercial a-c. system was regulated with sufficient accuracy of speed to enable its use for indicating time. Two devices then were developed making commercial a-c. time service possible. The first of these was a selfstarting synchronous motor which utilized residual magnetism to enable the rotor to start and run at synchronous ...

Proper time synchronization

Foundations of Physics, 1991
A clock-transport method of synchronization employing proper time is described that yields in any given inertial system the same result as slow transport, but that imposes no limit on transport proper speed. It is argued that because the method involves only the empirically validated kinematic invariant proper time, on which all observers must agree ...
