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.

Unicode C++

#include <CkJsonObjectW.h>
#include <CkDateTimeW.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.
    CkJsonObjectW json;
    json.UpdateString(L"ntp_server",L"pool.ntp.org");

    //  Query the NTP server for the current date/time.
    CkDateTimeW dt;
    success = dt.SetFromNtpServer(json.emit());
    if (success == false) {
        wprintf(L"%s\n",dt.lastErrorText());
        return;
    }

    //  Show the date/time in various formats..
    bool bLocalTime = true;
    wprintf(L"%s\n",dt.getAsTimestamp(bLocalTime));
    wprintf(L"%s\n",dt.getAsRfc822(bLocalTime));
    wprintf(L"%u\n",dt.GetAsUnixTime(bLocalTime));

    //  Sample output:

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