Answer 1

As mentioned 1 hour ago here, cppreference has good documentation on this: http://en.cppreference.com/w/cpp/io/manip/put_time

Specifically, you can get the format you described using the following format string:

std::cout  << std::put_time(std::localtime(&now_c), "%Y/%m/%d %T")

Answer 2

See this reference. It's actually the same as for the old strftime function, with some extra formats thrown in.
