The internal hardware clock is still ticking. But the linux kernel keeps
it's own time as soon as it's running. Hence after a suspend to sleep it
is out of sync and needs to be resynced with the hardware clock (as is
normally done on bootup).

Thinking about this, doesn't the fact that the clock keeps running in
suspend-to-ram mean that the processor keeps running then? I mean, some
part of the kernel must still be running to keep the time going, right?
Wouldn't this explain the power drain?
