Gnulib module: localtime
Portability problems fixed by Gnulib:
- On native Windows platforms (mingw, MSVC), this function works incorrectly
when the environment variable
TZ has been set by Cygwin.
Portability problems not fixed by Gnulib:
- On some platforms, this function returns nonsense values for
unsupported arguments (like 2^56), rather than failing:
- Native Windows platforms (mingw, MSVC) support only a subset of time
zones supported by GNU or specified by POSIX. See tzset.
