Good fix. :) I'll update the patch tonight (Aus time). If you don't
get to it first.

Yup. And we do mind if it runs on two separate days, but in the same
e.g. If you have a start time of 2pm and an end time of 10am, you
don't want two runs at 5pm and 7am only 14 hours apart.
Here is one thought:
QDate today = now.date();
QDate yesterday = today.addDays(-1);
QTime startTime = QTime(minhour, 0);
QTime endTime = QTime(maxhour, 30);
// Make laststart be the last time an 'ok to run' period started.
QDateTime startToday(today, startTime);
QDateTime startYesterday(yesterday, startTime);
QDateTime lastStart = (now >= startToday) ? startToday :
// Make lastend be the last time an 'ok to run' period ended.
QDateTime endToday(today, endTime);
QDateTime endYesterday(yesterday, endTime);
QDateTime lastEnd = (now >= endToday) ? endToday : endYesterday;
boolean OkToRun =
(lastEnd < lastStart) && // in an 'ok to run' period
(lastrun < lastStart); // Haven't yet run this period
This changes the inclusive end times to be exact times that are
offset by 30 mins. With this setup there is always at least a 30
minute period each day where it is ok to run.

A separate patch seems like a good idea. :) This is a change that
will require a whole lot more testing.
