Actually, it would be better to go with the definitions given by POSIX:
struct timespec st_atim Last data access timestamp.
For compatibility with earlier versions of this standard, the st_atime
macro shall be defined with the value st_atim.tv_sec.
(and so forth for ctime and mtime). This works if struct timespec is
layout-compatible with time_t followed by long; if not, then we've got
bigger problems to resolve first.
