Not really like you want, but you can put in your cron.
And by mail to your user or you can tell cron to which user send it will send the outpout of that commands... say some like:
09:19:23 up 3 days, 1:38, 1 user, load average: 0.02, 0.12, 0.13
Maybe it works for you.
Ah, I need to point that Debian had done a very good job tweaking cron, so there are some ways to put easier crontabs, from man 5 crontab:
Instead of the first five fields, one of eight special strings may
@reboot Run once, at startup.
@yearly Run once a year, "0 0 1 1 *".
@annually (same as @yearly)
@monthly Run once a month, "0 0 1 * *".
@weekly Run once a week, "0 0 * * 0".
@daily Run once a day, "0 0 * * *".
@midnight (same as @daily)
@hourly Run once an hour, "0 * * * *".
Now that you mention, if you want to know when the server you are reboots put a echo "I been restarted" on a crontab @reboot it's a nice way to know.
