Guys, I'm still having problems with our installation at the WMT. I got NTP to work on the remote Pi by using Ralph's ntp-wait work-round; this makes us wait for up to 10 minutes before the system syncs, but when it does the two clocks are exactly the same.
That's the good news. The bad news is that I have got very unreliable timekeeping from the realtime clock on the master Pi. Sometimes it appears to be keeping time, sometimes it gains or loses several minutes in an hour. One problem is that everything I try necessitates a delay of at least an hour or so before anything useful can be seen (and of course if it is keeping time then I have to wait even longer) ;-( The setup I have is that the master Pi has a RASClock purchased from ModMyPi, but sourced from Afterthought Software. The setup instructions are here: https://afterthoughtsoftware.com/products/rasclock. I originally posted on the ModMyPi Forum about this, but the response was fairly poor. One issue I had was that we have updated the installation on the two Pis to Raspbian Stretch; the last time I used one of these it was for the Bells software on Jessie. Now to the question. I was comparing the hwclock-set file on my Bells SD Card with the same file on the Sump Pi SD Card and I noticed a difference. The Bells config is missing two changes from the Afterthought website: * Comment out or remove the two lines which contain --systz buts that 's version that works! I've been reading the man page for hwclock to see what --hctosys and --systz do and have been struggling to see how relevant this might be and I note the reference to NTP. Bearing in mind that the NTP server is running on the master Pi (the same one that has the clock), I'm not sure if it's an issue or not. Does anyone have any thoughts on this? I'll quite happily fiddle with the settings, to try to fix this, but I'd like to know what I'm doing and the inherent delay means that it could be days before I know if I've fixed it. -- Terry Coles -- Next meeting: Bournemouth, Tuesday, 2017-10-03 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread: mailto:dorset@mailman.lug.org.uk / CHECK IF YOU'RE REPLYING Reporting bugs well: http://goo.gl/4Xue / TO THE LIST OR THE AUTHOR
