Defined in header
time_zone_link represents an alternative name for a time zone.
Users cannot construct
time_zone_link objects. The library implementation creates
time_zone_link objects when it initializes the time zone database and provides const access to these objects.
time_zone_link is not copyable but does have a defaulted move constructor and a defaulted move assignment operator. However, as users have only
const access to
time_zone_link objects, these functions cannot be called in user code without invoking undefined behavior.
