The last_write_time() function supplies the last modified date/time.

The symbolic_link_exists() helps with symlinks.

The bulk of the other attributes you mention are not currently supported by 
the filesystem library because we don't know a portable way to do so, even 
just between Wiindows and POSIX, let alone other systems. We've talked a 
lot about identifying some set of POSIX attributes that would sensibly map 
into a "read_only" query function, but no one has stepped forward to 
actually do a trial implementation.

HTH,
