date_time_add_milliseconds.cpp

Shows how to use xtd::date_time::add_milliseconds method.

    auto date2 = date1.add_milliseconds(1);
    console::write_line("Second date:   {0} ({1:N0} ticks)", string::format(date_format, date2), date2.ticks());
    console::write_line("Difference between dates: {0} ({1:N0} ticks)\n", date2 - date1, date2.ticks() - date1.ticks());
