I find the timestamps in kernel builds quite useful when doing work in feature branches. OTOH, back when I used sendmail as my MTA on my mail server I found the date in sendmail.cf useful as well. I don't use sendmail anymore so I am no longer worried about that one, but the kernel date one I would hate to see go away. -- John Baldwin
