fungal_net wroteYou mean in general how to set the time?
sudo date 012514512021.01 mmddhhmmyyyy.ss
If you mean time zone,
/etc/localtime -> /usr/share/zoneinfo/EuropeBelfast
% sudo ln -sf /usr/share/zoneinfo/EuropeBelfast /etc/localtime
on 66 at the boot@ module
# 66-env -t boot -e boot@ modulename
there is TZ and there is HARDWARECLOCK= UTC/localtime
i used the first one as i did find it eventually on the net...
all are great to have here for a reference. ty!
