(Unicode C++) Query NTP Server for Current Date/TimeDemonstrates how to query an NTP server to get the current date/time. Note: This feature was added in Chilkat v9.5.0.96.
#include <CkJsonObjectW.h> #include <CkDateTimeW.h> void ChilkatSample(void) { // 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; // Note: The SetFromNtpServer method is available starting in v9.5.0.96 for most Chilkat builds, but not all. // If the SetFromNtpServer method is not present, contact support@chilkatsoft.com for a hotfix build. // It should be available in all programming languages/platforms starting in v9.5.0.97 bool 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 } |
