set_timer(8)

NAME
set_timer - Assuming a fixed wakeup time in the BIOS, it modifies the system time, so that it will wake up after the specified sleep time.

SYNOPSIS
set_timer timer_enabled sleep_time

DESCRIPTION
set_timer is for BIOSes nvram-wakeup can't handle, because there is no way (known to the author) to change the wakeup time in the NVRAM. One of the reasons might be that the settings are stored in the upper nvram and the manufacturer is not cooperative in sharing the information how to access it. One of the reasons is that the checksum is computed in a way we can't see and the manufacturer is not cooperative in sharing the information how the checksum is computed. For such boards the wake up time must be set to 23:59:59 the day must be set to 31. If your board supports a month setting for the wakeup, set it to July. set_timer will modify the time in the hardware clock in a way that the computer will wake up at the right time. It will also remember, by which amount of time the clock was changed and restore the correct time on boot. The System should not update the hardware clock in the shutdown process. In Debian Woody set HWCLOCKACCESS=no in /etc/default/rcS

OPTIONS

timer_enabled
    if 0 disables the wakeup, otherwise enables it.

sleep_time
    the number of seconds from now, when the system should wake up
