[Cppcms-users] boost.locale and date formatting

[augustin <aug...@ov...>]

(second try to send this to the list)

Hello,

Speaking of boost(er).locale, I am having problems formatting dates.

I tried the simple example from here:
http://cppcms.sourceforge.net/boost_locale/html/formatting_and_parsing.html

#include <iostream>
#include <sstream>
#include <boost/locale.hpp>

using std::cout;
using std::endl;
using namespace boost::locale;

int main() {
        double now=time(0);
        cout << "Today is "<< as::date << now << " and tommorrow is " << 
now+24*3600 << endl;
        cout << "Current time is "<< as::time << now << endl;
        cout << "The current weekday is "<< as::ftime("%A") << now << endl;
}

g++ main.cpp -o run.main -lboost_locale

and the output is:

Today is 1.30439e+09 and tommorrow is 1.30448e+09
Current time is 1.30439e+09
The current weekday is 1.30439e+09

I tried with booster.locale that comes with cppcms, and I downloaded from svn 
and compiled the very latest boost.locale. I get the same result with both.

I'm sure I am missing something simple. 
Probably, I need to set the locale first, but it's not clear to me how to do 
it.

Also, a grip I have with most/all boost libraries, is that one never knows 
what option to pass to the linker:
http://stackoverflow.com/questions/3467153/is-there-an-intelligent-way-to-know-
the-name-of-the-library-to-link-to-at-compile
Is this platform/compiler dependent? Can't this kind of thing be documented?
Anyway, in this case, I found it was -lboost_locale.

For boost.locale, more, fully working, compilable examples would help.

-

Most boost libraries documentation are written for very experienced C++ 
developers. From a newbie perspective, I find most documentation very obtuse. I 
checked boost.date_time for a long while, and still couldn't understand enough  
to actually make use of it. I still have much to learn before I can understand 
a lot of the boost documentation.

-

Generally speaking, within the context of a cppcms application, what is the 
best/recommended way to format dates, times and such?
Basically, I have a unix timestamp, and I want to output it in human readable 
form, both in the UTC and locale timezone.


Thanks,

Augustin.
