Abstract: This disclosure describes techniques for delivering high-accuracy and high-precision clock synchronization in heterogeneous distributed computer clusters. For example, the disclosure describes a synchronization engine that sets efficient clock synchronization processes based on a cluster node's characteristics, pricing, precision, geolocation, and/or cluster topology, while in some cases using a combination of master clock data with internal atomic clocks of computers. The techniques described herein integrate the synchronization engine into a time synchronization process that may provide stability, versatility, precision and cost balance using technical improvements for characterizing timing system delivery channels.
