Use the pseudo user reboot on the last command:
http://manpages.ubuntu.com/manpages/natty/en/man1/last.1.html

In short, "last reboot" command will show each time the system has been
rebooted because the pseudo user reboot "logs in" each time the system
is started, from there you can do as you please with the output.
