Open 2 windows of this project On the first press "1" and on the second press "2" 1st step : the program calculate ping with an average of all pings 2nd step : project 1 send its "days since 2000" in P1 cloud variable -> project 2 receive and then calculate the time difference between its "days since 2000" and P1 variable considering the PING. 3rd step : project 2 send with P2 cloud variable a time value to project 1. Then both projects will say "EVENT" when their "days since 2000" is greater than P2. This way, both project are sync on time and are able to run something at the same time
