Linux keeps it's own clock (called the system clock) which it uses for
various things. This clock is set from the hardware clock at each reboot.
You can set the system clock in linux with many various tools,
control-panel has a utility to do so, hwclock(?) will also let you set the
system time from the hardware clock and vice versa. "date" also does
wonders as root.

CUDA is the powermanagement unit, all recent macs have them, or something
similar. This is what makes your mac go nighty-bye-bye after some defined
amount of time of inactivity. Reseting this makes all your power setting
go away, resets the PRAM and does some other things which I forget.
Under the standard Apple Problem Diagnosis Workflow this is normally
listed right before "Replace CPU, Replace Logic Board." (eg: it's pretty
much the last thing you can do to solve problems with your mac unless you
have spare CPU's and logic boards hanging about)
