The reason I want to get rid of the every-second timer is to save power when
operating on battery with no refclocks.
If you have a PPS, you have to take an interrupt every second. I'm not a
wizard on that area. It would be interesting to know if you can get useful
interrupt responses when starting from a power-save mode. Similarly, can you
wakeup in time to get data from a serial port without dropping any
characters? It may be that power-save just won't happen if you are using
Moving the PPS processing out of ntpd doesn't change any of that.
These are my opinions. I hate spam.
