No.  The charging only happens when the laptop is on, as far as I can
tell from the circuit.  It doesn't happen when the laptop is suspended.

However, a small amount of charging will run the clock for quite a long
time.

I don't have a clue how much charging is required to charge the clock
battery from a fully flat state.  Perhaps Richard knows.

Good idea.

I searched for ntp-set-clock using Google:

	site:wiki.laptop.org "ntp-set-clock"

There was no other reference than the firmware version when it was
added.  So a place to post these instructions would be good.

Setting the date and time within Sugar is reasonably well covered here:
http://wiki.laptop.org/go/Sugar_Control_Panel#Time
.. but I recall that some builds don't even have ntpdate, and the
instructions don't account for that.

Older instructions can be found here:
