typedef std::chrono::system_clock isc::stats::SampleClock

Define clock type.

Note: : we use the system clock i.e. the wall clock because this clock can be converted from and to standard Unix time (time_t).

Definition at line 34 of file observation.h.

Pointer to the statistics context.

Definition at line 85 of file context.h.

typedef std::chrono::system_clock::duration isc::stats::StatsDuration

Defines duration type.
