Google writes a range that stays in one half of the day with the meridiem on
the closing time only, "1:00 – 3:00 PM" for one to three in the afternoon.
The 24-hour conversion only saw times carrying their own AM/PM, so the
opener stayed "1:00" beside a converted "15:00". The closing meridiem is
handed back to an opener that has none before converting; a range spelled
on both sides, the 12h display and lines without a meridiem are untouched.
