Assume there is a time series of records for 100 days.
{{{
MyModel.objects.all().order_by('-date').last()
}}}
Returns the oldest record in the time series, which is same as returned
by:
{{{
MyModel.objects.all().order_by('-date')[:10].last()
}}}
This is not intuitive. Should return the 10th newest record, the slice
operator [:10] should be honoured.
