Way to find install date for a linux system

[nemp]

Is there a way to find the date a particular instance of linux OS was installed ?

syslog should tell you, but you won't need all of it:

sudo cat /var/log/installer/syslog | less

To exit the view, just type "q", without the quotes.

The date in syslog should be your install date. I'm currently working on a new setup, and my output begins with:

Dec 26 05:49:31

install hardinfo from the repositories then click on the operating system line

you can also do this (just another way to get the same info)

at root prompt type "ls -al /var/log/installer/syslog"

results should be similiar to below:

-rw------- 1 root root 230110 2009-04-13 13:29 /var/log/installer/syslog

note the date here "2009-04-13 13:29"
