DateTime - Add or Subtract Seconds

Demonstrates the AddSeconds method to add or subtract a number of seconds from a date/time.

Note: This example is only valid in Chilkat v9.5.0.65 or later.

C++

#include <CkDateTime.h>

void ChilkatSample(void)
    {
    CkDateTime dateTime;

    dateTime.SetFromCurrentSystemTime();

    std::cout << "Current time: " << dateTime.getAsTimestamp(false) << "\r\n";

    dateTime.AddSeconds(1);
    std::cout << "Current time + 1 second: " << dateTime.getAsTimestamp(false) << "\r\n";

    dateTime.AddSeconds(-2);
    std::cout << "Current time - 1 second: " << dateTime.getAsTimestamp(false) << "\r\n";

    //  Add 30 days (60 * 60 * 24 * 30)
    dateTime.AddSeconds(60 * 60 * 24 * 30);
    std::cout << "Current time + 30 days: " << dateTime.getAsTimestamp(false) << "\r\n";

    //  Sample output for test run on 2-Dec-2016: 

    //  	Current time: 2016-12-02T12:59:13Z
    //  	Current time + 1 second: 2016-12-02T12:59:14Z
    //  	Current time - 1 second: 2016-12-02T12:59:12Z
    //  	Current time + 30 days: 2017-01-01T12:59:12Z
    }
