How to determine timer offset between tiles?

Postby luator » Wed Mar 20, 2019 2:49 pm

Hello,
on this knowledge base page it is mentioned that the timers of separate tiles have a offset because "the
tiles may come out of reset on different times". Now we are wondering how we can measure the this offset.
We want to compare timestamps from different tiles for accurate synchronization between the tiles.
