I don't know how all the desktop parts work together. However, it is a
waste of resources to let your computer run only because for example you
need to access it remotely in a couple of hours/days/month, or have it
do some task. And I see many user that keep their machines running, just
because they do not see a way to schedule it.
The desktop environments would help saving energy, if their shutdown
dialogs could by default provide the option (button/checkbox) to
schedule a restart.

allow to set restart/resume time

Bug description:
Linux provides a simple way to schedule a restart event that is
particularly usefull in conjuction with initiating or scheduling a
shutdown or suspend.
rtcwake -m on -s <seconds-util-start-event>
Howerever, just as the shutdown command it requires root privileges.
The particular command given in the example above avoids that rtcwake does any switching into another power state (mode -m stays on).
This allows that the power state fully handled by the regular installed power managment (userspace) tools, which is often more stable than the pure kernel/rtcwake, especially on resume.
To test it, just schedule a wake event, then do a regular
shutdown/suspend. Later, the real time clock will trigger the
scheduled power up event and the machine comes back up.
