Yes, sir, feel free to use it. My call sign is KD9EFV, name is Kevin.
I am now in the process of switching over all my Pi's and VMs running Debian family OSs, even at home.
If you would like, I can write up what I did for my gpsd/chrony/time server portion to allow all
my machines sync a standard time, without internet access ( or with home network )
BTW, I am an Enterprise level 3 Help Desk by trade. I am a VERY lazy SysAdmin
(meaning I will work VERY hard to minimize the need to do lots of hands on
maintenance). I am just getting into serious Python (part of another project I help on
motionEye and motionEyeOS). I am by no means a 'programmer', though... <LOL>
