systemd anacron.service problem, runs only once after boot

[Chris Green]

My cron.daily tasks (the executables in /etc/cron.daily) are only ever
getting run once after a system boot.  Up until July 22nd (I'm not
sure if that date is significant) they all ran, as designed, every day,

What I see from systemctl is:-

    chris at q957$ date

    chris at q957$ systemctl status anacron.service

    Aug 05 11:11:07 q957 systemd[1]: anacron.service: Consumed 3.441s CPU time, 1.5M memory peak, 0B memory swap peak.

As you can see anacron.service was run once (just after a roboot) on August
5th at 09:10 and then it never runs again.

It was working perfectly until 22nd July, why is it now deactivating the anacron
service after running it once?
