 abstract = {Forms of synchrony can greatly simplify modeling, design, and verification of distributed 
systems. Thus, recent advances in clock synchronization protocols and their  
adoption hold promise for system design. However, these protocols synchronize the distributed  
clocks only within a certain tolerance, and there are transient phases while  
synchronization is still being achieved. Abstractions used for modeling 
and verification of such systems should accurately capture these imperfections that cause 
the system to only be "almost synchronized." In 
this paper, we present approximate synchrony, a sound and tunable abstraction 
for verification of almost-synchronous systems. We show how approximate synchrony 
can be used for verification of both time synchronization protocols and 
applications running on top of them. We provide an algorithmic approach for 
constructing this abstraction for symmetric, almost-synchronous systems, a subclass 
of almost-synchronous systems. Moreover, we show how approximate synchrony 
also provides a useful strategy to guide state-space exploration. We have 
implemented approximate synchrony as a part of a model checker and used it to 
verify models of the Best Master Clock (BMC) algorithm, the core component of 
the IEEE 1588 precision time protocol, as well as the time-synchronized channel 
hopping protocol that is part of the IEEE 802.15.4e standard.},
