[Qt-interest] New Date and Time Features in Qt5?

[Thomas Meyer]

Hi,
from the Qt Assistent for Qt 4.7: QDate Class Reference:
...


        No Year 0

There is no year 0. Dates in that year are considered invalid. The year 
-1 is the year "1 before Christ" or "1 before current era." The day 
before 0001-01-01 is December 31st, 1 BCE.
...


The astronomical date have a year 0. In astronomical date the JD 0.0 is 
-4712 Jan 01.
In civil date (QDate) JD 0.0 is -4713 Jan 01.

And I want a astronomical extension. JD is the same at all, but the 
conversion into the
calendar is not the same.

Thomas
