Sure, you can use the "strftime" function from the "time.h" library in C++, and the following format specifier to convert the date/time to ISO 8601 format: "%Y%m%dT%H%M%SZ". You can then use the "gmtime" or "localtime" function to convert the date/time to the desired UTC time zone.

use C plus to transmitt date/time in ISO 8601 format (YYYYMMDDThhmmssZ) and UTC time zone.
Sure, you can use the following code in C++ to transmit date/time in ISO 8601 format and UTC time zone:
```c++
#include <iostream>
#include <iomanip>
#include <chrono>
int main() {
// Get current date/time in UTC
auto now = std::chrono::system_clock::now();
auto now_time_t = std::chrono::system_clock::to_time_t(now);
// Convert to local time
struct tm local_tm;
gmtime_s(&local_tm, &now_time_t); // use gmtime_s for Windows, gmtime for other OS
// Output in ISO 8601 format
std::cout << std::put_time(&local_tm, "%Y%m%dT%H%M%SZ") << std::endl;
return 0;
}
```
This code uses the `std::chrono` library to get the current date/time in UTC, then converts it to the local time zone using the `gmtime_s` function (which is used for Windows, but you can use `gmtime` for other operating systems).
Finally, it uses the `std::put_time` function to output the date/time in ISO 8601 format ("%Y%m%dT%H%M%SZ").
