Top Forums UNIX for Dummies Questions & Answers Can we change the file created date? Post 302586133 by jim mcnamara on Friday 30th of December 2011 08:11:51 AM

The file creation date (ctime) is not really the creation date in unix, it is the last time the inode data and some other metadata was modified.

chmod modifies ctime. assume the file is -rwxr-xr-x (755) then
Code:
chmod 755 filename  # you have to own the file to do this

will set ctime to now.

Linux chattr command can also change the ctime.
