Issue ID: 21134 Summary: time_t should probably be defined as a 64-bit type on x86-64 Product: D Version: D2 Hardware: All OS: Windows Status: NEW Severity: normal Priority: P1 Component: druntime Assignee: nob...@puremagic.com Reporter: andrej.mitrov...@gmail.com https://github.com/dlang/druntime/blob/349d63750d55d078426d4f433cba512625f8a3a3/src/core/sys/windows/stdc/time.d#L42 This definition seems to have remained unchanged since at least 2008 and probably older: https://github.com/dlang/druntime/blob/6837c0cd426f7e828aec1a2bdc941ac9b722dd14/import/stdc/time.d#L49 This is around the time x64 Windows originally started getting released. But nowadays MSDN says that `time_t` defaults to being a 64-bit type: https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/time-time32-time64?view=vs-2019 > time is a wrapper for _time64 and **time_t is, by default, equivalent to > __time64_t**. --
