可能是有些地方又重新定义64位的了。 我也遇到过这个问题。只能是取64位的低32位。
time_t类型不是由gcc定义的，而是由系统库定义的。在Linux上，这是glibc，它在 time.h标题中定义了 ...
FILETIMEを取得したら、FileTimeToSystemTime関数を使用して値をシステム時刻に変換できます。 従来のコード例 前のセクションのコード例は、任意のアーキテクチャに適しています。 ただし、32 ビット アーキテクチャ用にビルドし、_USE_32BIT_TIME_Tを定義すると、time_tは 32 ビット値にな...
Easily find the exact time difference with the visual Time Zone Converter. Find meeting times for your contacts, locations and places around the world. Never warp your brain with time zone math again.
「ctime_s、_ctime32_s、_ctime64_s、_wctime_s、_wctime32_s、_wctime64_s」を参照してください。 構文 C コピー char *ctime( const time_t *sourceTime ); char *_ctime32( const __time32_t *sourceTime ); char *_ctime64( const __time64_t *sourceTime ); wchar...
32-bit time_t should be enforced A backport of fix for "BUG40092- Storage engine API uses time_t datatype". Starting from MSVC C++ 2005 (v8), the default size of time_t is changed from 32-bit to 64-bit. As the result, the binaries built with pre-v8 MSVC C++ do not work with...

The library makes the false assumption that time_t is equivalent to long. To avoid the year 2038 problem Linux distributions like Debian and Ubuntu have moved to using 64-bit time_t on 32-bit architectures like ARMv7. Now we see test failures like: FAIL tltest-timespec.c:169 -2147483648.9...
ctime does not respect _USE_32BIT_TIME_T define. There is no #ifdef _USE_32BIT_TIME_T section within the file so only *64 functions and structures are used and hence the compilation fails when _USE_32BIT_TIME_T is defined. Microsoft Visual Studio Professional 2022 (64-...
a new library transition again on 32-bit archs. Won't they also be caught again in binary NEW, for those packages that don't have the same runtime library package name in experimental? It seems to me there's ample opportunity to catch such mistakes if they happen. ...
