Member Data Documentation

baseYear

int16_t const ace_time::ZoneInfoHigh::ZoneContext::baseYear

Base year for tiny years.

Unused.

Definition at line 98 of file ZoneInfoHigh.h.

kMaxUntilYear

const int16_t ace_time::ZoneInfoHigh::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 56 of file ZoneInfoHigh.h.

kMaxYear

const int16_t ace_time::ZoneInfoHigh::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 64 of file ZoneInfoHigh.h.

kMinYear

const int16_t ace_time::ZoneInfoHigh::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 74 of file ZoneInfoHigh.h.

startYearAccurate

int16_t const ace_time::ZoneInfoHigh::ZoneContext::startYearAccurate

Start year of accurate transitions.

kMinYear indicates -Infinity.

Definition at line 92 of file ZoneInfoHigh.h.

untilYearAccurate

int16_t const ace_time::ZoneInfoHigh::ZoneContext::untilYearAccurate

Until year of accurate transitions.

kMaxUntilYear indicates +Infinity.

Definition at line 95 of file ZoneInfoHigh.h.
