A very simple plugin to execute any command without the drift of say executing every 1200 ticks - the TPS will never be exactly 20.0.

I recommend the crontab.guru cron editor with a nice explanation.
You can see how the config works in the default, basically for every cron expression you can set a list of commands to be run.

The cron tasks can be reloaded from the config.yml with /ccmd reload, which requires the permission croncommand.reload. Please do not edit lastrun.txt directly. [I like trains]

Notes

I developed this plugin in my free time. Please use the Issues page on GitHub (linked above) if you believe you found a bug, or would like a new feature added. I cannot guarantee any form of support, or any updates.

What I can guarantee however, is that leaving a 1* review won't get you far. Please be kind, and I will do my best to help you.
