It seem posix defines
(http://www.opengroup.org/onlinepubs/009695399/basedefs/sys/stat.h.html)

  time_t    st_atime   Time of last access. 
  time_t    st_mtime   Time of last data modification. 
  time_t    st_ctime   Time of last status change. 

st_birthtime/st_btime seems to be an BSD extension, AFAICS,
so we may want to skip this one.  It falls back to ctime
though, if the system does not support it.

This is POSIX, however, and, as Sylvain said, not many
middleware implementations will support the full set.

Best, Andre.
