time_t is on windows 64-bit

[mezen]

Windows time_t differs from Unix time_t: the Windows version is not bit depending and always 64. In C and only on 32 bit you can use a macro to switch to 32-bit time_t, but that is not the default and not recommended.

Windows source: https://learn.microsoft.com/en-us/cpp/c-runtime-library/reference/time-time32-time64

time is a wrapper for _time64 and time_t is, by default, equivalent to __time64_t. If you need to force the compiler to interpret time_t as the old 32-bit time_t, you can define _USE_32BIT_TIME_T. We don't recommend _USE_32BIT_TIME_T, because your application may fail after January 18, 2038; the use of this macro isn't allowed on 64-bit platforms.

But on Unix and Linux systems time_t is bit depended.

I hope {$IFDEF WINDOWS} is the correct compiler directive for Indy.
