You could use a "cluster ssh" to run your commands at the same time on all hosts. You could run a script on each server that just run an infinite loop and, at a give time, runs a command.
IMO, if one is going to a bash script, it would be better to: - calculate time to elapse until the target cmd is to run - use a sleep (maybe adjusted a tad to allow for latency)

If all the nodes are in sync, timewise, this should get them all going close to each other.
