I used to say that, until I learned how to do it.

That updates ctime for all files, and that may be undesirable. See here:
[root at numbat modprobe.d]# \ls -l
total 36
-rw-r--r-- 1 root root  810 Jun 15  2007 blacklist
-rw-r--r-- 1 root root  833 Mar 25  2007 blacklist-compat
-rw-r--r-- 1 root root   83 Nov 30 03:28 blacklist-firewire
-rw-r--r-- 1 root root 5717 Mar 25  2007 modprobe.conf.dist
[root at numbat modprobe.d]# \ls -l --time=ctime
total 36
-rw-r--r-- 1 root root  810 Jun 15  2007 blacklist
-rw-r--r-- 1 root root  833 Jun 15  2007 blacklist-compat
-rw-r--r-- 1 root root   83 Dec  5 09:58 blacklist-firewire
-rw-r--r-- 1 root root 5717 Jun 15  2007 modprobe.conf.dist
[root at numbat modprobe.d]#

June 15 would be when I installed this system. Dates further back are 
when my vendor changed them (Scientific Linux 5.0).
