Detailed Description

Data structures that describe the mid resolution zoneinfo persistence format.

by the AceTimeTools compiler. It has a 1-minute resolution for AT, UNTIL, STDOFF; a 15-minute resolution for DST offset (similar to ZoneInfoLow). But it also uses 2-byte year fields supporting year range of [-32767,32765] (similar to ZoneInfoHigh).

The BrokersMid.h file provides an abtraction layer which converts these low-level fields into a semantically consistent API which can be used by the AceTime classes.

The various zoneinfo database files (e.g. zonedb, zonedbx, zonedbc) will use one of these persistence formats, as defined by infos.h. (The ZoneInfoMid.h persistence format was used at some point during the development, but it is current not used by any of the zone*db database files.)

See also DEVELOPER.md for an overview of the ZoneInfoXXX layer.
