incorrect time in email notifications

hi,
I have activated email notifications.
every hour I get an email about cron.
but it says the system time is 2 hours behind.
looking in the system, the time is given correctly.
this looks like a time-zone problem.
but where ??
thanks
Fred

I changed the timezone in Date & Time to Europe/Amsterdam
and the time is shown correctly.
you want me to use the command timedatectl
as RemoteDesktop is refusing me, right now, I am trying this with SSH
but it says the command is not found

the emails about this say the following:

Zitat

/etc/cron.hourly/fake-hwclock:
Current system time: 2016-10-18 12:17:01
fake-hwclock saved clock information is in the future: 2016-12-06 15:11:00
To force the saved system clock backwards anyway, use "force"
/etc/cron.hourly/openmediavault-flushmailq:
postsuper: Deleted: 1 message

yes, oke, thanks

I added myself to the groups root and sudo
or is that not the best way to go ??
