Вопрос о формате файла базы данных часовых поясов

я читаю из файлов часовых поясов, сгенерированных из базы данных Olson , чтобы узнать, когда меняются часовые пояса и на что они меняются. Формат файлов часовых поясов описан в tzfile.h .

Что касается моего вопроса, я буду использовать данные, которые я получил для Европы / Рима.

Возможно, он работает правильно, потому что мой вывод правильно соответствует тому, что говорит timeanddate.com . Например, моя программа правильно говорит, что:

28 марта 1982 г. 02:00:00 часовой пояс изменится на GMT +2.000000.

26 сентября 1982 г. 03:00:00 часовой пояс изменится на GMT +1.000000 .

Это подтверждается здесь: http://www.timeanddate.com/worldclock/clockchange.html?n=215&year=1982

Однако я не уверен, нужно ли мне использовать tzh_ttisstdcnt и tzh_ttisgmtcnt.

Из tzfile.h:

Тогда есть tzh_ttisstdcnt стандартные / настенные индикаторы, каждый хранится как однобайтовое значение; они говорят, есть ли время перехода, связанное с местным временем указаны типы как стандартное время или время настенных часов, и используются, когда файл часового пояса используется для обработки часового пояса в стиле POSIX переменные среды.

Наконец, есть tzh_ttisgmtcnt UTC / местные индикаторы, каждый из которых хранится как однобайтовое значение; они говорят, есть ли время перехода, связанное с местным временем типы были указано как UTC или местное время, и используются, когда используется файл часового пояса в обработке часового пояса в стиле POSIX переменные окружения.

Я обнаружил, что каждый "тип времени" (структура ttinfo) имеет байты isstd и isgmt. Это 6 "типов времени" для Европы / Рима:

  Тип 0, CEST, DST?  = 1, GMT + 2, isstd?  = 1, isgmt?  = 0
  Тип 1, CET, DST?  = 0, GMT + 1, isstd?  = 1, isgmt?  = 0
  Тип 2, CEST, DST?  = 1, GMT + 2, isstd?  = 0, isgmt?  = 0
  Тип 3, CET, DST?  = 0, GMT + 1, isstd?  = 0, isgmt?  = 0
  Тип 4, CEST, DST?  = 1, GMT + 2, isstd?  = 1, isgmt?  = 1
  Тип 5, CET, DST?  = 0, GMT + 1, isstd?  = 1, isgmt?  = 1
 

tzfile.h делает его похожим на isstd, а isgmt сообщает вам, как сохраняется время перехода (gmt vs localtime). Однако мой код в настоящее время предполагает, что все времена переходов сохраняются как GMT. Вывод моей программы соответствует timeanddate.com для всех 6 типов переходов.

Кроме того, я не понимаю, как типы 0 и 1 могут быть стандартными, а не gmt. Я думал, что это стандартное время по Гринвичу.

Любое объяснение было бы отличным.

Изменить:

Похоже, что мои выходные данные почти совпадают с данными на timeanddate.com , когда я игнорирую isstd и Параметры isgmt. В настоящее время я интерпретирую все времена перехода как GMT:

Типы перехода для Рима:

новый тип 0: isdst = 1 смещение = 7200 аббревиатура = 0 isstd = 1 isgmt = 0

новый тип 1: isdst = 0 смещение = 3600 аббревиатура = 5 isstd = 1 isgmt = 0

новый тип 2: isdst = 1 смещение = 7200 аббревиатура = 0 isstd = 0 isgmt = 0

новый тип 3: isdst = 0 смещение = 3600 аббревиатура = 5 isstd = 0 isgmt = 0

новый тип 4: isdst = 1 смещение = 7200 аббревиатура = 0 isstd = 1 isgmt = 1

Данные для Рима (при условии, что все время перехода указано как GMT):

The starting timezone is GMT+1
