1.14.2: Problem in rtcwake

[Zvi Vered]

Hello,

I'm using busybox 1.14.2 under vanilla linux 2.6.27.35 on Pentium-M board.

I''m trying to run "rtcwake" to put the CPU to sleep:

When I tried: rtcwake -s 10 -m standby
I got:
wakeup from "standby" at  Thu Jan  1 01:45:31 1970
rtcwake: short write

When I tried: rtcwake -s 10 -m mem
I got:
wakeup from "mem"  at Thu Jan  1 01:45:31 1970
rtcwake: short write

According to a link I found, the normal messages should be someting like:

wakeup from "standby" at Thu Jan  1 01:45:31 1970
Syncing filesystems ... done.
Freezing user space processes ... (elapsed 0.00 seconds) done.
Freezing remaining freezable tasks ... (elapsed 0.00 seconds) done.
Suspending console(s)
Restarting tasks ... done.

What am I doing wrong ?

Thanks,
