I don't know how it works where you live, but in the UK the autumn

triggered twice.
BUT, we are specifically addressing the OP's situation and the time in his crontab ISN'T within the
time frame of when BST (the OP is in the UK) starts/ends.
Yes, that's clear. I was simply answering the general question (since
you said "to/from DST"), even though it doesn't apparently affect cron
as such, as documented in the manual.

Note this has happened a few times this year, (approx 1 in 64 x) so not
related to DST changes anyway. Might be due to chrony clock resyncs I
suppose but I think something stranger is going on here or something
silly and obvious in what I am doing.
I will have a more detailed look at the system and my backup shell
script and create a simple test cron job to see if it shows the same
thing ...
