Hi I want to check if a time in System::DateTime is smaller than the current time. I would like to use this code:

    time_t now;
    time(&now);
    if (difftime(this->monthCalendar1->SelectionStart, now)) {

    }

But the this->monthCalendar1->SelectionStart is a System::DateTime and the difftime() want to use time_t so how can I convert a System::DateTimeobject to time_t.

The dupe links covers both to and from cases. – NathanOliver Feb 05 '16 at 15:44
What's `System::DateTime`, there's no such thing in Standard C++. If it's .NET please specify explicitly – Andriy Tylychko Feb 05 '16 at 15:44
