ITIME is a tool used for changing file times, useful for hiding changes. Does not work on Linux Mint Serena KDE.
Note: atime = Access time; mtim = Modified time; ctime = Creation time.

Usage: ./itime.i686-pc-linux-gnu-2.2.14-5.0 [-hdDvf] [-a atime] [-m mtime] [-c ctime] file
-h Help
-d Debugging
-D Detailed debugging
-v verbose
-f force changes
atime, mtime, & ctime are in seconds

You need to be able to read the 'file' and write to /dev/kmem
