PI seems to return the earliest 7 departures. While
the PTV Timetable API supports filtering patterns by datetimes, the
behaviour of this argument is not reliable --- it appears to filter by day
only, returning the earliest 7 departures of a different day. It is
recommended that departures are retrieved via the <code><a href='departures.html'>departures</a></code>
function.</p>
