Date/Time Expires Within N Seconds/Minutes/Hours/Days

Demonstrates the how to tell if a date/time is within N seconds, minutes, hours, or days of the current system time. C++

#include <CkDateTime.h>

void ChilkatSample(void)
    {
    CkDateTime dt;

    //  Set to the current system date/time.
    dt.SetFromCurrentSystemTime();
    std::cout << "Now: " << dt.getAsTimestamp(true) << "\r\n";

    //  Add 10 minutes, making the date 10 minutes in the future.
    dt.AddSeconds(600);
    std::cout << "10 minutes from now: " << dt.getAsTimestamp(true) << "\r\n";

    //  Is the date/time within 10 seconds of expiration (i.e. within 10 seconds of now)?
    bool b = dt.ExpiresWithin(10,"seconds");
    std::cout << "Expires within 10 seconds: " << b << "\r\n";

    //  Does the date/time expire within 5 minutes?
    b = dt.ExpiresWithin(5,"minutes");
    std::cout << "Expires within 5 minutes: " << b << "\r\n";

    //  Does the date/time expire within 15 minutes?
    b = dt.ExpiresWithin(15,"minutes");
    std::cout << "Expires within 15 minutes: " << b << "\r\n";

    //  Does the date/time expire within 1 hour?
    b = dt.ExpiresWithin(1,"hour");
    std::cout << "Expires within 1 hour: " << b << "\r\n";

    //  Does the date/time expire within 1 day?
    b = dt.ExpiresWithin(1,"day");
    std::cout << "Expires within 1 day: " << b << "\r\n";

    //  Output:

    //  	Now: 2017-05-05T23:48:00-0500
    //  	10 minutes from now: 2017-05-05T23:58:00-0500
    //  	Expires within 10 seconds: False
    //  	Expires within 5 minutes: False
    //  	Expires within 15 minutes: True
    //  	Expires within 1 hour: True
    //  	Expires within 1 day: True
