struct SuspendingClock

SuspendingClock can be considered as a system awake time clock. The frame of reference of the Instant may be bound machine boot or some other locally defined reference point. This means that the instants are only comparable on the same machine in the same booted session.

This clock is suitable for high resolution measurements of execution.
