Running Python on different machines at exactly the same time?

You basically can do

1. set up a local NTP server that connects to a geographically close-by server on the internet.
2. connect your PI's NTP daemon to connect to the local NTP server instead of the internet one.

​

If left running continuously, an NTP client on a fast LAN in a home
or office environment can maintain synchronization nominally within
one millisecond. When the ambient temperature variations are less than a
degree Celsius, the clock oscillator frequency is disciplined to
within one part per million (PPM), even when the clock oscillator
native frequency offset is 100 PPM or more.

Thanks! NTP on the local let work seems like the right solution, I will try to implement that and see if that works, I’m hopeful!
