The reminder crons run at 09:00 in the instance's TZ but computed today
in UTC, so east of Greenwich a trip reminder arrived a day late. A day
the job did not run also lost that day's trip reminders for good: the
match was 'starts exactly N days from today'. Trips now record the start
date a reminder went out for, and the job sends every reminder that is
due and not yet sent. The active-trip redirect and the upcoming
reservations use the instance's date and clock as well.
