wakeupat(1M)                                                      wakeupat(1M)


NAME
     wakeupat - request that system power back on at a future time

SYNOPSIS
     wakeupat time [ date ] [ +increment ]

DESCRIPTION
     wakeupat allows you to specify a time at which the system will power on
     by itself.  Currently only Indy, Indigo2, OCTANE , O2 and Challenge M
     support this feature.  The syntax for specifying the time is identical to
     that of the at(1) command.

     If the system is rebooted after this command is used, the wakeupat time
     is cleared and must be reissued.  If the system is not powered off before
     the given time, the command has no effect (that is, the system will not
     power back on as soon as powered off).

     Systems may have a limited range for which power up requests are valid.
     For Indy and Indigo2, the time must be within one week from the current
     date.  On OCTANE the time must be within one month of the current date.
     Note that the requested date is programmed into the poweron circuitry at
     the time the system is shutdown or powered off, and will not take effect
     if the system shuts down abnormally.  If the date at the time of system
     shutdown has been changed so as to be later than the requested power on
     time, the system will not power back on automatically.

     The time can be specified as 1, 2, or 4 digits.  One and two digit
     numbers are taken to be hours, four digits to be hours and minutes.  The
     time can alternately be specified as two numbers separated by a colon,
     meaning hour:minute.  A suffix am or pm can be appended; otherwise a 24-
     hour clock time is understood.  The suffix zulu may be used to indicate
     GMT.  The special names noon, midnight, now, and next are also
     recognized.

     An optional date can be specified as either a month name followed by a
     day number (and possibly year number preceded by an optional comma) or a
     day of the week (fully spelled or abbreviated to three characters).  Two
     special ``days'', today and tomorrow are recognized.  If no date is
     given, today is assumed if the given hour is greater than the current
     hour and tomorrow is assumed if it is less.  If the given month is less
     than the current month (and no year is given), next year is assumed.

     The optional increment is simply a number suffixed by one of the
     following:  minutes, hours, days, weeks, months, or years.  (The singular
     form is also accepted.)

     Thus legitimate commands include:
          l.  wakeupat 0815am Jan 24 wakeupat 8:15am Jan 24 wakeupat now + 1
          day wakeupat 5 pm Friday wakeupat 1900 thursday next week
