      <cpp‎ |chrono‎ |time zone
       
       
      Date and time library
       
       
      template<class Duration>

      auto to_local(conststd::chrono::sys_time<Duration>& tp)const

         ->std::chrono::local_time<std::common_type_t<Duration,std::chrono::seconds>>;
      (since C++20)

      Converts thesys_timetp to the correspondinglocal_time in thistime zone.

      Contents

      [edit]Parameters

      tp - a time point to be converted

      [edit]Return value

      Thelocal_time associated withtp and this time zone.

      [edit]Notes

      The precision of the result is at leaststd::chrono::seconds, and will be finer if the argument has finer precision.

      [edit]Example

      Run this code
      #include <chrono>#include <iostream> int main(){constauto some_zone_name{"Australia/Sydney"};constauto time_pt_utc{std::chrono::system_clock::now()};std::cout<<"Current time UTC is:\t\t "<< time_pt_utc<<'\n'; try{std::cout<<"Current time local is:\t\t "<<std::chrono::current_zone()->// may throw                      to_local(time_pt_utc)<<'\n'<<"Current time "<< some_zone_name<<" is:\t "<<std::chrono::locate_zone(some_zone_name)->// may throw                      to_local(time_pt_utc)<<'\n';}catch(conststd::runtime_error& ex){std::cout<< ex.what()<<'\n';}}

      Possible output:

      Current time UTC is:              2025-02-10 13:38:13.233872158Current time local is:            2025-02-10 16:38:13.233872158Current time Australia/Sydney is: 2025-02-11 00:38:13.233872158
