<import package="base" />
Providing the current timestamp externally allows the system to be
wholly deterministic.
It also captures the state of the data in time,
so re-calculating in the future (e.g. using the summary pages)
will yield the same result.

system (clock time), as it should be perceived" />
This system does not handle its own arthiemtic to figure out the
current date components from the given timestamp.
