UiTimeline class
A grouped, reverse-chronological activity timeline.
Events are grouped by their UTC calendar day. Use dayTotals together with onLoadMore to progressively reveal older events within individual days. Date and time label builders make the component localization-friendly without imposing an internationalization package on applications.
