  • That particular topic is 6 years old, there have been a lot of changes since then. Have you tried to locate more recent information? – Taegost Jul 05 '16 at 13:18

It is true that the initial creation date is not recoverable if the file has been modified. The on-disk i-node only tracks the last time ACCESSED and the last time MODIFIED. Both of those data are returned by the stat( char * ) or fstat( int ) system calls and are available in the st_atime and st_mtime fields, respectively, of struct stat.

SUGGESTION: if the files were installed once and nothing has been added or deleted, then the last time MODIFIED of the DIRECTORY THAT CONTAINS THE FILES would be the datum that you seek.
