NAME

       setalarm - sets the system to start and run a script at specified times.

SYNOPSIS

       setalarm [ -p ] [ [h]h:mm ] [ -o offset ] [ command ]

       setalarm [ -p ] [ -c m h dom mon dow ] [ -o offset ] [ command ]

       setalarm [ -p ] [ -u utc ] [ -o offset ] [ command ]

       setalarm -d

DESCRIPTION

       This  should  be  run  as root, unless using the -p option. The time to wake the computer can be given in
       three possible formats.  The simplest is just a time, written hh:mm or h:mm. This time is interpreted  as
       the  earliest  time  in the future when that time occurs.  If the -c option is provided, a cron-formatted
       recurrence (minute hour day_of_month month day_of_week) may follow. Special times such as  "@hourly"  are
       not accepted.  With the -u option, the time to wake the computer should be provided in UTC format.

       command  is  run  at  the  closest  time  in  the future that matches the recurrence rules or at the time
       specified using an exact hh:mm or UTC time. For this to occur, the computer is woken up  several  minutes
       in advance to allow for boot time. By default, this "offset" is 5 minutes, but can be changed with the -o
       option, in which case the computer is woken up offset minutes in advance. To  ensure  that  the  computer
       will wake given the -c option, crontab entries are made in root's crontab to rerun setalarm as necessary.

       With  the  -p  option,  setalarm  will not make any changes to the system wake time or to root's crontab.
       Instead, setalarm just prints the time, in UTC, at which the computer would be set to wake  up  with  the
       given input.

       Given the -d option, setalarm removes all alarms.

NOTES

       setalarm  was  created  for  use  with  wakeup,  a fully customizable and extensible talking alarm clock.
       However,  it  is  generally  usable  as  a  convenient  wrapper  for  setting  the  system  wakeup   (see
       http://www.mythtv.org/wiki/ACPI_Wakeup for details about ACPI wakeup)
