> What are the actual requirements in the regulations?

For the Euro markets
https://www.emissions-euets.com/time-stamping-and-business-clocks-synchronisation
max deviation of 100 microseconds or 1 millisecond or 1 second,
granularity 1 microsecond or 1 millisecond or 1 second,
depending on who you are and other latencies.

During the development of these regulations drafts were calling for
1 microsecond.  The above results came after closed-session powwows
with folks from BIPM and other timing labs.
