# Job

## Cron

The new min jobs per day for cortex will be 1 every 10 seconds (8640). This allows up to 6 \* \* \* \* \* type cron jobs until limits are reached. This is a minimum allowance which supercedes the maximum allowance if it is lower. Effectively Math.max( min, env max). The new default is also 8640 per day.x

@job('1 * * * *', {
  name: 'update_check',
