Member functions
tzdb::locate_zone
tzdb::current_zone

[edit]

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

The classtzdb represents a copy of theIANA time zone database. Users cannot construct atzdb and can only obtain read-only access to one via the free functionsstd::chrono::get_tzdb_list andstd::chrono::get_tzdb.

[edit]Member objects

Member object	Description
`version`	Astd::string that contains the version of the database
`zones`	A sortedstd::vector<std::chrono::time_zone> containing description of time zones
`links`	A sortedstd::vector<std::chrono::time_zone_link> containing description of alternative names of time zones (links)
`leap_seconds`	A sortedstd::vector<std::chrono::leap_second> containing description of leap seconds

[edit]Member functions

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