Ah, now it makes sense.
My script to collect the data runs via cron which ensures the script
only ones once at DST change, so I am missing the data point for 01:00
BST (rather, my loader script assumes the entry for 01:00 on the 25th
Oct is GMT so there is nothing inserted.
I've fixed in now based on this - I allow a 7200 second gap which
allows the graph to continue uninterrupted.
Thanks for your help on this!
