I can not use `date`-command because the busybox version has limited 
options and I don't want use the util-linux-`date`.

Touching the rtc disables the wakeup function on some motherboards. 
Therefore I'm storing the actually time at first and then I'm setting 
the wakeup time.

Nvram-wakeup is messing arround with all the bits. I would recommend to 
do a CMOS-Reset.

I testet ACPI-wakeup on four differend Motherboard, neither of them need
