Is there a way to check when I installed OS X?

I am about to do a clean install of Leopard and I wanted to know if there's a way to check and see when I last installed it...
 
Interesting question, as I was wondering the same a while back and never pursued an answer. But just now I had an epiphany.

Look at the info on the user you created in the Finder. It will show you the date created. Mine is 17 Mar, 2008 - Happy St Paddy's day, and the arrival of my 24" iMac!
 
Wow... I was hoping that wasn't true. My Aluminum iMac has become painfully slow in about a month's time. I really think it's Safari 3.1 and 10.5.2 that are causing problems.

I can't wait for my Tiger disks to arrive from Apple. GRRR.
 
So the criterion is "be you"? :)

The file isn't there on my system; there are plenty of files in /var/log but no OSInstall.custom (or OS-anything, for that matter).
 
yeh OSInstall.custom definitely shows the install date. mine is 2007-10-26 04:59:16 which is correct.

i did a clean install so it may be missing for users that did an upgrade or archive.

to open it copy and paste "/var/log/" into "Go To Folder…" in Finder's Go menu and drag OSInstall.custom onto TextEdit's dock icon.

or for the CLI folks

Code: 
cd /var/log

Code: 
nano OSInstall.custom
