5 POSIX specification:@* @url{https://pubs.opengroup.org/onlinepubs/9699919799/functions/utime.html}
9 Portability problems fixed by Gnulib:
12 The times that are set on the file are affected by the current time zone and
13 by the DST flag of the current time zone on some platforms:
14 mingw, MSVC 14 (when the environment variable @code{TZ} is set).
16 On some platforms, the prototype for @code{utime} omits @code{const}
17 for the second argument:
20 On some platforms, @code{utime("link-to-file/",buf)} succeeds instead
21 of failing with @code{ENOTDIR}.
25 Portability problems not fixed by Gnulib:
28 On some platforms, this function mis-handles trailing slash:
31 This function cannot set full timestamp resolution. Use
32 @code{utimensat(AT_FDCWD,file,times,0)}, or the gnulib module @code{utimens},
