Please bottom-post.

TMPTIME controls "/tmp".

I have no idea how the deletion of the contents of "/vat/tmp" on
Ubuntu. I've always assumed that Ubuntu behaved like RHEL and cleared
items in "/var/tmp" that are older than 30 days but a quick look in
"/etc/init*" and "/etc/cron*" as well as root's crontab didn't yield
anything. And the only Ubuntu box that I can check at the moment has a
completely empty "/var/tmp" so I can't even check how old the oldest
file in it is.
