Update timestamps of entire system heirarchy?
 

What's the safest way to update the timestamp of every file that has a specific date on the system?

I recently installed slackware onto a raspberry pi, and during the install and shortly after i did not set the clock, so many system and user files appear as the unix epoch 0 (jan 1st 1970).

Because of OCD, i want to update them. I'm weary of using "touch" however, as i don't want to break anything.

Is it safe to do something like this?
However, i only want to "touch" files that match, Jan 1 1970.

Thanks.

Include a test of -atime +n or -ctime +n,

n being slightly smaller than the number of days since jan 1st 1970.

Check your command first, of course.
