[edit] Exceptions
std::runtime_error if this is the first reference to the time zone database and the time zone database cannot be initialized.
[edit] Notes
A call to this function that is the first reference to the time zone database will cause it to be initialized.
[edit] Example
Run this code
#include <chrono> #include <iostream> int main() { try { const std::chrono::zoned_time cur_time { std::chrono::current_zone(), // may throw std::chrono::system_clock::now() }; std::cout << cur_time << '\n'; } catch(const std::runtime_error& ex) { std::cerr << ex.what() << '\n'; } }
Possible output:
