The old code is just plain wrong for negative julian days. Replaced
with plain math from The Calendar FAQ [1], which is correct for all
julian days, provided you use mathematical integer division (round to
negative infinity) rather than c++11 integer division (round to zero).

While the conversion code works for up to around JD +/- (2^63/4), we
only use an int for the year in the API, so this patch limits minJd()
and maxJd() to 1 Jan (2^31) BC and 31 Dec (2^31-1) AD, respectively.
Note that while the new conversion code looks like it would be more
expensive than the old, gcc will in fact be able to optimize it to be
slightly faster (probably because x86 hardware implements round to
negative infinity, and so GCC manages to optimize floordiv to a single
instruction, compared to the three instuctions needed for operator/).
In the following test application, run with a release mode Qt and
redirecting stderr to /dev/null, I measured an improvement from
6.81s +/- 0.08s to 6.26s +/- 0.16s user time over five runs on an
otherwise idle x86_64 system.
int main(int, char *[])
{
int year, month, day;
qint64 jd;
for (qint64 i = Q_INT64_C(-1048576) ; i < Q_INT64_C(1048576); ++i) {
QDate::fromJulianDay(i).getDate(&year, &month, &day);
jd = QDate(year, month, day).toJulianDay();
qDebug() << jd << year << month << day;
}
}

This suggestion keeps track of the most left node.
The point is that constBegin() becomes a lot faster.
That speeds up iteration a bit, and makes it O(1) to get the
first element. The penalty in insert and remove is very small.
On large trees it seems to be less than 1%.
It should be noticed that constBegin() is a very common hint
on my planned change to 5.1, and this opperation will without
this patch cost 2 x log N. One when the user calls the hint
with begin - and one where it is compared with begin.
Other std::maps has a very fast begin(). E.g
