Detailed Description

A source of time for systems and containers.

Now() returns the time since some fixed starting point that the clock chooses. It never decreases. Only differences between two readings of the same clock mean anything.

A system or a container holds a pointer to its clock and does not own it, so the clock must outlive whatever uses it. The default is the real steady clock (SteadyClock). A ManualClock lets a test move time by exact amounts without waiting.
