DataStore::update_interval_boundary_dates() protected WC 1.0

Updates start and end dates for intervals so that they represent intervals' borders, not times when data in db were recorded.

E.g. if there are db records for only Tuesday and Thursday this week, the actual week interval is [Mon, Sun], not [Tue, Thu].

{} It's a method of the class: DataStore{}

No Hooks.

Return

null. Nothing.
