Convert start and end points of free/busy periods to UTC immediately, fixing
incorrect conversion of zone-specific dates where the user's time zone is
inappropriately used instead of the specified time zone, occurring because the
specified time zone does not accompany any date object when initialising the
period (being indicated by separate attributes that are not provided) and thus
the user's time zone is then used as a fallback.
