# hyper-p2p-cron-gossip
Distributed **cron scheduling** with local `tick()` and remote `cron-fire` gossip.
**Category:** Scheduling & queues · **Protocol:** `cron-gossip/v1`
## When to use
Cluster-wide periodic tasks, `@every` intervals, or classic five-field UTC cron strings shared on a topic.
## When not to use
Sub-second precision timers, single-process `setInterval` only, or durable job queues (use deadline/activity queues).
## Quick start
```js
const { HyperP2PCronGossip } = require('hyper-p2p-cron-gossip')
const cron = new HyperP2PCronGossip({ topic: process.argv[2] })
await cron.ready()
cron.schedule('@every 5s', 'heartbeat')
setInterval(() => cron.tick(), 1000)
```
