The Raspberry Pi has no battery powered hardware clock, so it needs to fetch time via NTP and store it via
fake-hwclock to not start at 1970 again after a power-loss. When the device is running the CPU keeps track of time.
How is "running" defined here?
Examples of what I mean follow. When I do
where the CPU does not power down, does the clock stop for some seconds or does it even get reset? When I do
sudo shutdown -h now
but do not pull the power cord (PWR LED still on), does the clock continue running or does it stop or does it reset?
