Of the three commands the first one gets no complaint, with the second
attempt I did add the "sudo" preface and still I'm denied:

daryl at daryl-A780L3C:~$ SECS=`date -u --date "2013-08-29 10:50:00" +%s`
daryl at daryl-A780L3C:~$ sudo echo 0 > /sys/class/rtc/rtc0/wakealarm
bash: /sys/class/rtc/rtc0/wakealarm: Permission denied
daryl at daryl-A780L3C:~$ sudo echo $SECS > /sys/class/rtc/rtc0/wakealarm
bash: /sys/class/rtc/rtc0/wakealarm: Permission denied

See! I remain open to suggestions.
