Class Hash

java.lang.Object

hudson.scheduler.Hash

public abstract class Hash
extends Object

Generates a pseudo-random sequence of integers in the specified range.

CronTab supports tokens like '@daily', which means "do it once a day". Exactly which time of the day this gets scheduled is randomized --- randomized in the sense that it's spread out when many jobs choose @daily, but it's at the same time stable so that every job sticks to a specific time of the day even after the configuration is updated.
