Another update - reading the locale docs, i found out I have to install a
default global locale to use date_time

Right now what I do is this -

	std::tm created_at = r.get<std::tm>("created_at");
	c.topics[i].created_at = mktime(&created_at);

created_at is of data type date_time.

Is there any library function to make it less complicated so I dont have
to first convert tm to time_t and then to date_time?

Thanks
Petr
