The slot count property of the sliding timeline index is the number of slots in the timeline.

Example

The above example uses a relative base time of `today`, which is reevaluated each time the search engine load is updated. The index will map a total of seven days, with one days worth of items mapped to an individual slot. As time moves forward, the limits of the timeline are automatically adjusted. Items falling outside the new timeline are removed from the data-store and associated indexes.
