This might be a problem. I don't think that *time attributes are supported in
HelenOS at all at the moment. Access time will almost certainly never be
implemented because it's a bad thing(TM).

I can imagine.

These are only for ported applications that make use of out POSIX compatibility
library that provides a limited level of POSIX-like C library (we use it for
PCC and GNU binutils). For these posix_xxx gets mapped to xxx via preprocessor
macros. Nevertheless since the OS does not suport *time attributes, using
libposix will not help you, it does not have any way of getting these
attributes now.
