That’s just sloppiness.
The information that familiarity gives you is “WTF does this field means”, and it’s the only thing that’s actually there. How you get a value and how a value is formatted are things no amount of expertise will save you from having to tell the computer, and thus you can’t just forget about.
(And let me guess, the software recommended install is a docker image?)
I’ll second people here in pointing that you are better allowing calls from your family during the “Do Not Disturb” than trying to set-up things not to call you during that time. Your phone almost certainly has a setting that allows “favorite contacts” or something like it.
It has a better configuration orthogonality :)
Just about this part:
Or you might set up an sFTP service to accept a GUI connection from a client like FileZilla.
FileZilla has been a troublemaker for decades (not because the software itself, but the OP won’t get it right), and sFTP requires an extra service.
I’d recommend he get WinSCP or another scp client.
So, you need a unix time value followed by 000?
That first part you can calculate with
date +%s -d '2024-07-02 12:00'
