Date and time classes for Arduino that support timezones from the TZ Database.
ZoneInfo Data Files

These are internal representations of the zoneinfo data from the IANA TZ database. Library users should treat these data objects as opaque. They should be referenced only by the specific basic::kZone* or extended::kZone* identifiers defined in the src/zonedb and src/zonedbx directories. The internal structure of these data types will change when the internal implementations change.

There are 5 core data types: ZoneContext, ZoneRule, ZonePolicy, ZoneEra and ZoneInfo. Each data type (except ZoneContext, which is in the internal:: namespace) is duplicated into 2 namespaces (basic:: and extended::) for use with BasicZoneProcessor and ExtendedZoneProcessor respectively.
