For packages you currently have installed via Play or .apk installation you could go into /data/app and look at the dates on the .apk files. If you flashed something in recovery it'll show up as August 1 1970 or August 1 2008 or whatever generic date. As said previously, Titanium Backup uses this if you sort by date lol.
Edit, example (most mine are 25 July since I restored them through Titanium Backup):
