I have a node app that has one-off scheduled tasks. Between node-cron and real Linux cron, I went with real cron because node-cron just polls every second, which is extremely inefficient and I'm on a free tier. How does your library work in this regard? If my node server is down, will my scheduled tasks still execute? I notice you have a .start() method, what does that do? Is it polling periodically?
