Query NTP Server for Current Date/Time

Demonstrates how to query an NTP server to get the current date/time.

Note: This feature was added in Chilkat v9.5.0.96.

C++

#include <CkJsonObject.h>
#include <CkDateTime.h>

void ChilkatSample(void)
    {
    bool success = false;

    //  Specify the NTP server domain.
    //  Information is passed in a JSON object to allow for any unanticipated future optional information that might need to be provided.
    CkJsonObject json;
    json.UpdateString("ntp_server","pool.ntp.org");

    //  Query the NTP server for the current date/time.
    CkDateTime dt;
    success = dt.SetFromNtpServer(json.emit());
    if (success == false) {
        std::cout << dt.lastErrorText() << "\r\n";
        return;
    }

    //  Show the date/time in various formats..
    bool bLocalTime = true;
    std::cout << dt.getAsTimestamp(bLocalTime) << "\r\n";
    std::cout << dt.getAsRfc822(bLocalTime) << "\r\n";
    std::cout << dt.GetAsUnixTime(bLocalTime) << "\r\n";

    //  Sample output:

    //  2023-10-31T09:43:27-05:00
    //  Tue, 31 Oct 2023 09:43:27 -0500
    //  1698745407
