My son warned me about becoming root, I am still quite a newbie, and it
shows, below is what happened when I tried the first option:

 daryl at daryl-A780L3C:~$ SECS=`date -u --date "2013-08-29 11:45:00" +%s`
daryl at daryl-A780L3C:~$ sudo sh -c echo 0 > /sys/class/rtc/rtc0/wakealarm
bash: /sys/class/rtc/rtc0/wakealarm: Permission denied
daryl at daryl-A780L3C:~$ sudo sh -c echo $SECS > /sys/class/rtc/rtc0/wakealarm
bash: /sys/class/rtc/rtc0/wakealarm: Permission denied
daryl at daryl-A780L3C:~$

I'm still looking at bricks, this shouldn't be that complicated, should it?
