DYNAMIC_TIME_ZONE_INFORMATION

構造体

サイズx64: 432 バイト / x86: 432 バイト

サイズ=各フィールドのバイト数(x64/x86 で異なる場合は x64/x86 と併記)。x64/x86 列=フィールドのバイトオフセット(HSPで dupptr / lpoke / wpoke 等に使用)。

フィールド

フィールド	型	サイズ	x64	x86	説明
Bias	INT	4	+0	+0	UTCとローカル時刻の差(分)。ローカル時刻 = UTC + Biasの関係になる。
StandardName	WCHAR	64	+4	+4	標準時の名称を表すWCHAR配列(最大32文字)。
StandardDate	SYSTEMTIME	16	+68	+68	標準時へ切り替わる日時を表すSYSTEMTIME。
StandardBias	INT	4	+84	+84	標準時に追加で適用するバイアス(分)。通常0。
DaylightName	WCHAR	64	+88	+88	夏時間の名称を表すWCHAR配列(最大32文字)。
DaylightDate	SYSTEMTIME	16	+152	+152	夏時間へ切り替わる日時を表すSYSTEMTIME。
DaylightBias	INT	4	+168	+168	夏時間に追加で適用するバイアス(分)。通常-60。
TimeZoneKeyName	WCHAR	256	+172	+172	レジストリのタイムゾーンキー名を表すWCHAR配列。動的DSTルール参照に使う。
DynamicDaylightTimeDisabled	BOOLEAN	1	+428	+428	動的な夏時間調整を無効化するか否かのフラグ。TRUEで無効。

HSP3.7/3.8 は構造体機能が無いため4byte整数配列(dim)+peek/poke で操作(32/64bitでサイズ・位置が異なる場合はタブで分割)。IronHSP は NSTRUCT(#defstruct/stdim/->)で32/64bit共通。
