Actually, the hardware clock has always been set to local time. Had
to: Used to have Windows XP installed (this box is 11+ years old) as a
multi-boot with Linux, and as you know Windows needs the hardware
clock set to local to work correctly. I've just keep it that way. .

Actually, it's the other way around. hardware clock is local time, but
Stretch thinks it's UTC. (I have Wheezy on here to, but it's configured
Just going to use hwclock and the --localtime option to reset it.
Haven't been able to find any other way to do so.

I alway install ntp, but I want everything timewise configured
appropriately before I do so.
Thanks for you advice.
