Since a fresh install from Debian 8 to 9, this started to happen.
Looking in to the matter, I've found this so far.

Looking over the net people with other Linux had the same issue, but is
not my bios clock, the time is correct there. Cheking the clock it show
a a few seconds of difference. Others suggest messing with ntp,
/etc/adjtime and a dozen other "solutions" for different Linux distros,
is there any effective?

The bugreport show that this has been patched, anything else I could do
to stop running system check/clean every time I boot?
Thanks
