How to make a common timer for all Node.js processes?

Question

Node.js

I use pm2 for daemonization and clustering.
I run pm2 start app.js -i 88 copies of the process on 8 cores.
There was a need to use a common timer loop for all processes.
Is it even possible to do this with pm2? How to enter into the database?
Or redo the entire architecture through Cluster?

Answer 2

One timer process makes publish in redis
The rest, by subscribe, catch this notification and do their own logic
