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

[Jason H]

I've written software that has been distributed to hundreds of  customers, 
including Japan and Korea. In all my years of supporting that software, I only 
ever came across one computer that was set to the non common-era style, and that 
was the Buddhist calendar. 


I don't recommend supporting the Mayan calendar at this time, as they are coming 
up on their Y23,000 problem late next year. (Best to add support for /after/ 
they rollover) We can probably drop support for the Christian calendar as well 
since their rapture is scheduled for this Saturday. 


Good or bad, I think the common era calendar (with timezones) is all we need. 

(Yes, that's supposed to be some humor up there)

Thanks for all the responses, even if it did get side-tracked a bit on leap 
seconds and nano-seconds.  Personally I'm not convinced such a level of 
accuracy is required for most Qt users, but I'll keep it in mind when making 
suggestions about ways Qt could allow QTime to be sub-classed to create your 
own specialised time classes.

Timezones is obviously a very popular feature, I believe Qt are working on 
this as a requirement for Qt Mobility so hopefully we get a good result there.

Date maths and date/time periods are also another popular request, with an 
existing merge request, and KDE also has date maths code we can look at.

I'm a little surprised no-one commented on the formatting options available in 
Qt, are people really happy with just YMD options?

Also any comments on alternative calendar systems (Islamic, Chinese, Japanese 
Era, etc)?  Does anyone get complaints from end users in the Middle East and 
Asia that their dates are not correctly localised to their Windows/OSX system 
settings?  If there's not much demand for this then I'll need a Plan B :-)

Thanks again.

John.
