std::chrono::tzdb

Member functions

tzdb::locate_zone

tzdb::current_zone

Defined in header <chrono>
struct tzdb;		(since C++20)

The class tzdb represents a copy of the IANA time zone database. Users cannot construct a tzdb and can only obtain read-only access to one via the free functions std::chrono::get_tzdb_list and std::chrono::get_tzdb.

Member objects

Member object	Description
version	A std::string that contains the version of the database
zones	A sorted std::vector<std::chrono::time_zone> containing description of time zones
links	A sorted std::vector<std::chrono::link> containing description of alternative names of time zones (links)
leaps	A sorted std::vector<std::chrono::leaps> containing description of leap seconds

Member functions

locate_zone	locate a time zone with the given name (public member function)
current_zone	return the local time zone (public member function)
