Portability problems fixed by Gnulib:

Portability problems not fixed by Gnulib:

• This function is missing on some platforms: Minix 3.1.8, mingw, MSVC 9, Interix 3.5, BeOS.
• The declaration of this function lacks const in the second argument on some platforms: OSF/1 5.1.
• On some platforms, this function mis-handles trailing slash: FreeBSD 7.2, Solaris 9.
• This function cannot set full timestamp resolution. In particular, some platforms incorrectly round rather than truncate. Use utimensat(AT_FDCWD,file,times,0), or the gnulib module utimens, instead.
• On some platforms, utimes (file, NULL) fails to set the file's timestamp to the current time: glibc 2.3.3.
• On some platforms, utimes failed on read-only files when utime worked fine. glibc 2.2.5.

Extension: Gnulib provides a module ‘utimens’ that works around these problems and allows to set the time with nanosecond resolution (as far as supported by the file system).
