Hi Ken,
Thanks, that works, problem solved. FSGetCatalogInfo (&ref, kFSCatInfoCreateDate.. is a better option to obtain creation date when you need to get NTFS file's date too.
Thanks to all responded,
Angelo.

You should use UCConvertUTCDateTimeToCFAbsoluteTime() and CFDateCreate(). Since CFDate is toll-free bridged with NSDate, you can just cast the result. (You do have to be mindful of memory-management issues, of course.)
You can also feed the CFAbsoluteTime value to +[NSDate dateWithTimeIntervalSinceReferenceDate:], since the reference date is the same between the two.
Regards,
Ken
