How do I convert between time zones (C++20/23)?

Converting between time zones in C++20 and later is facilitated by the `` library, specifically with the `` extensions for dealing with time zones. Below is an example that demonstrates how to perform a conversion between time zones.

#include #include #include #include #include // Include the date library for time zone support using namespace std; using namespace std::chrono; int main() { using namespace date; // Define the starting time (UTC) sys_days today = floor(system_clock::now()); zoned_time utc_time = zoned_time{"UTC", today}; // Convert to a different time zone (e.g., America/New_York) zoned_time new_york_time = convert("America/New_York", utc_time); // Output the original and converted time cout << "UTC Time: " << utc_time << endl; cout << "New York Time: " << new_york_time << endl; return 0; }
