Hmm, something is definitely wrong in here. I sometimes _do_ get
something back.
root@amd:~# s2ram
Switching from vt9 to vt1
switching back to vt9
root@amd:~#
root@amd:~#
root@amd:~# cd /sys/class/rtc/rtc0
root@amd:/sys/class/rtc/rtc0# ls
date dev device@ name power/ since_epoch subsystem@ time
uevent wakealarm
root@amd:/sys/class/rtc/rtc0# cat wakealarm
2051629528
root@amd:/sys/class/rtc/rtc0# cat power/wakeup
root@amd:/sys/class/rtc/rtc0# cat wakealarm
2051629528
root@amd:/sys/class/rtc/rtc0# date +%s
1190285030
root@amd:/sys/class/rtc/rtc0# echo 1190285050 > wakealarm
root@amd:/sys/class/rtc/rtc0# s2ram
Switching from vt9 to vt1
switching back to vt9
root@amd:/sys/class/rtc/rtc0#
root@amd:/sys/class/rtc/rtc0#
root@amd:/sys/class/rtc/rtc0# cat wakealarm
root@amd:/sys/class/rtc/rtc0# cat wakealarm
root@amd:/sys/class/rtc/rtc0# date +%s
1190285229
root@amd:/sys/class/rtc/rtc0# cat wakealarm
root@amd:/sys/class/rtc/rtc0#
Also, is there some documentation for wakealarm?
sh-3.1$ cd Documentation/
sh-3.1$ grep -ri wakealarm .
...is it time in seconds? In UTC? In whatever timezone rtc clocks are
using? It does not seem to work for me :-(.
