utime
=====

POSIX specification:
 https://pubs.opengroup.org/onlinepubs/9699919799/functions/utime.html

Gnulib module: utime

Portability problems fixed by Gnulib:

  * The times that are set on the file are affected by the current time zone and by the DST flag of the current time zone on some platforms: mingw, MSVC 14 (when the environment variable TZ is set).

  * On some platforms, the prototype for utime omits const for the second argument: mingw, MSVC 14.

  * On some platforms, utime("link-to-file/",buf) succeeds instead of failing with ENOTDIR. macOS 11.1.

Portability problems not fixed by Gnulib:

  * On some platforms, this function mis-handles a trailing slash: Solaris 9.

  * This function cannot set full timestamp resolution.  Use utimensat(AT_FDCWD,file,times,0), or the gnulib module utimens, instead.
