[Joda-interest] What is the thought of the joda key concepts?How you lead to its now?

[吴冉波 <wu...@gm...>]

I thought and search a long time before the courage to ask this question.

I am curious about the key concepts of joda-time. It shows something
amazing clear to its problem, that is the first thought when I read it
years ago. After using it more and more in my projects, I realize I won't
be wrong with problem about time any more(of course, hope :-). It all
relied on the concepts of joda-time.

As a programmer, the problems like time always taught me much even years
later: First, something (like time) is so common. It is everyday and
everywhere in the real world. But when I want to do it right, something bad
always happen.Reading and using the books about programming concepts helps
a little, not enough to solve it right. We need the knowledge of real world
and profiling it with our own head.Software design it is.

So that's the reason why I ask the problems.
What is the thought of the joda key concepts? How you lead to its now?
I think it should be very valuable for many people. Maybe some articles
already be published? ( I failed google it with these keywords.)
Tell me. Hope not too silly(or my English too poor).
