1. Kill ntpd if running
To what purpose???????
If NTPD is running, your clock should be very close to the correct time.
I can't see anything useful to be gained by restarting NTPD.
For cases when ntpd is running and the offset and drift are way off. Your PPS
measurements may be invalid while ntpd is running.
Once you have your clock running, leave it running 24x365. An
uninterruptable power supply is a good thing to have; it lets you ride
out the brown outs and drop outs. Another good thing to have is a
gasoline powered generator for those times when the power company really
screws up! You should know BEFORE the power goes off what your
emergency plan expects you to do..
This method is an option for setups not running 24x7 or environments where
stable power is not available. You don't need hours to stabilize the NTP clock
discipline, as long as the offset and frequency/drift is within acceptable
bounds.
Please use your "Return" key! That last line runs off the right side of
my screen.
