    /proc/acpi/alarm can't be set correctly, here is a sample:
    
    [root@localhost /]# echo "2006 09" > /proc/acpi/alarm
    [root@localhost /]# cat /proc/acpi/alarm
    2007-12-09 09:09:09
    [root@localhost /]# echo "2006 04" > /proc/acpi/alarm
    [root@localhost /]# cat /proc/acpi/alarm
    2007-12-04 04:04:04
    [root@localhost /]#
    
    Obviously, it is wrong, it should consider it as an invalid input.
    
    after this patch:
    
    [root@localhost /]# echo "2008 09" > /proc/acpi/alarm
    -bash: echo: write error: Invalid argument
    [root@localhost /]#
