Clock syntonization using network effect and/or adaptive stochastic control

A system comprising:

• a non-transitory computer-readable medium comprising memory with instructions encoded thereon for syntonizing machines in a network;
• and
• one or more processors that, when executing the instructions, cause the system to perform operations, the operations comprising:
• for different pairs of machines, estimating a drift between the pair of machines based on probe records storing transit times of probes transmitted between the pair of machines, at least one of the machines producing timestamps based on a reference clock;
• for different loops of at least three machines in the network, calculating a loop drift error based on a sum of the estimated drifts between pairs of machines around the loop;
• and
• adjusting estimated absolute drifts of the machines based on the loop drift errors, wherein the absolute drift of a machine is defined relative to the reference clock.
