OpenBSD 7.4

In cron(8) and crontab(5), add support for random offsets when using ranges with a step value in cron. This extends the random range syntax to support step values. Instead of choosing a random number between the high and low values, the field is treated as a range with a random offset less than the step value. This can be used to avoid thundering herd problems where multiple machines contact a server all at the same time via cron jobs.
