◆ kMaxUntilYear

const int16_t ace_time::ZoneInfoLow::ZoneContext::kMaxUntilYear = 32767

static

The maximum value of untilYear.

This value is used to represent the sentinel value "-" in the UNTIL column of the TZDB files which means "infinity". Must be greater than ZoneRule::kMaxYear which represents the value "max" in the TO and FROM columns of the TZDB files.

Definition at line 58 of file ZoneInfoLow.h.

◆ kMaxYear

const int16_t ace_time::ZoneInfoLow::ZoneContext::kMaxYear = kMaxUntilYear - 1

static

The maximum value fromYear and toYear.

This value is used to represent the sentinel value "max" in the TZDB database files. Must be less than ZoneEra::kMaxUntilYear which is used to represent the entry "-" in the UNTIL column of the TZDB files.

Definition at line 69 of file ZoneInfoLow.h.

◆ kMinYear

const int16_t ace_time::ZoneInfoLow::ZoneContext::kMinYear = -32767

static

The minimum value of fromYear and toYear.

This value is used for ZoneRule entries which are synthetically generated for certain time zones which do not naturally generate a transition for the database year interval specified by the ZoneContext. This value is guaranteed to be earlier than any explicit year in the TZDB database, which guarantees that all time zones have at least one transition.

Definition at line 82 of file ZoneInfoLow.h.

◆ startYearAccurate

int16_t const ace_time::ZoneInfoLow::ZoneContext::startYearAccurate

Start year of accurate transitions.

kMinYear indicates -Infinity.

Definition at line 103 of file ZoneInfoLow.h.

◆ untilYearAccurate

int16_t const ace_time::ZoneInfoLow::ZoneContext::untilYearAccurate

Until year of accurate transitions.

kMaxUntilYear indicates +Infinity.
