All syncing programs have to use the same protocol syncing
to the "second", i.e. it may be one second or 5 seconds.

Since the protocol is primitive all syncing programs
are primitive to the "second", i.e. it may be one second or
5 seconds.

The issue here is not syncing but the accuracy of the
PC time clock or any way to use an expansion
board with highly accurate clock so that the syncing
is reduced to a minimum.
