Re: [Cppcms-users] booster::locale::as ...

[mawan s. <ma...@gm...>]

I want to create date time from string, for example input from form date
time field. i currently work from srign and covert to integer year, month ,
date, hour .. etc and use std:tm to reusable date time.
Second, I want to converting from string date time from data base
(2016-09-09 08:07:07) to date time , and to string date time.

Is booster::locale can handle it? or should i use c++ std::tm and
std:time_t?

Thanks before ..
Regards
