Thanks for that pointer, Gary.  I've been collecting NTP data for some 
years now, and I'm basically happy with this.

My thoughts at the moment are:

- to disable the OS from setting the RTC - I gather there's an 11-minute 
time controlling this

- to have the RTC cause an interrupt (say every minute) and record the 
PPS-disciplined system time when that happens.

There's no suggestion of using the RTC to control system time other than 
at initial power-up.  It's more an exercise to measure the RTC itself.

Cheers,
David
