Classes
struct	Mads::ClockSample
	One four-timestamp exchange, all fields microseconds since the Unix epoch: t1/t4 read from the initiator's clock, t2/t3 from the responder's. More...
struct	Mads::ClockOffsetResult
	Result of a clock-offset measurement: offset_us added to a clock in the measured domain yields broker-host time (broker_host_clock - domain_clock). source/hops/origin_agent_id/seq are Agent-level bookkeeping the estimator does not fill in – only estimate()'s own offset_us/delay_us/samples/valid are computed from the timestamps. More...
class	Mads::ClockOffsetEstimator
	Accumulates ClockSamples and returns the classic NTP "best of N": the retained sample with the smallest round-trip delay, i.e. the one least polluted by queuing delay along the path. More...
class	Mads::ClockConsensus
	Per-clock-domain adoption of the smallest-delay measurement heard from any agent sharing that domain (§2.1 of the design): agents on one host announce their own measurements, and every agent applies this same deterministic rule – so they converge on one offset without an election. More...
struct	Mads::HostSkewStat
	Snapshot of one host's passive clock skew, as computed by HostSkewStats::snapshot() at a given instant. More...
class	Mads::HostSkewStats
	Thread-safe sliding-window tracker of per-host clock skew, fed by mads top's passive mode: for every received message, record (local_rx_time - payload's own timestamp field), both as epoch microseconds. No protocol at all – works against any existing MADS deployment, since timestamp/hostname are already stamped on every published message by Agent::publish(). More...

Namespaces
namespace	Mads

Enumerations
enum class	Mads::ClockSource { Mads::None = 0 , Mads::Broker = 1 , Mads::Peer = 2 }
	Which mechanism produced a ClockOffsetResult. More...

Functions
ClockOffsetResult	Mads::estimate (const ClockSample &s)
	NTP-style estimate from one four-timestamp exchange.
