--- Comment #5 from David Eckardt <[email protected]> --- > I don't know what would happen if you called toISOExtString at > compile-time. I'd have to test it. It might not even work due to using a > pointer comparison. I tried it: import std.datetime.systime: SysTime; import std.datetime.timezone: UTC; pragma(msg, SysTime.fromUnixTime(0, UTC()).toISOExtString()); fails with “typecons.d(2145): Error: reinterpretation through overlapped field `stripped` is not allowed in CTFE”. Consider SysTime.fromUnixTime(0, LocalTime()) at compile-time: The `is` comparison` could really cause a bug here, using UTC instead. However, static immutable ctfe = SysTime.fromUnixTime(0, LocalTime()); fails with “concurrency.d(2488): Error: static variable `lock` cannot be read at compile time”. So we are safe. --
