# cron module

## Introduction
The cron module is a scalebox public module similar to the cron function under UNIX, which periodically sends messages to each sub-module to start related timing operations.

Each line defines the timing operation for a module, including timing operation interval definition and module name, separated by commas.

# comments for cron.txt
@every 1m,mod0
@every 1m30s,mod1
```

The definition part of the timing operation interval refers to:
