I'd like to find out (ideally via terminal) how long my operating system (Ubuntu 12.04 LTS) has been installed - either that or the date on which the installation took place. Is this possible? If so, how can it be accomplished?

If you are confident the hardware clock was correct at the time Ubuntu was installed, you can look at the files in /var/log/installer, specially /var/log/installer/syslog:

$ sudo head -n1 /var/log/installer/syslog
May 27 19:03:08 ubuntu kernel: imklog 5.8.11, log source = /proc/kmsg started.
