These are simple, easy to use convenience properties for creating short-term scheduled events and produces a cleaner, easier reading syntax than using the other various methods to produce the same result, for example: Schedule.On(DateRules.Tomorrow, TimeRules.Noon, MyScheduledEventMethod); Also fixes typo in FuncDateRule constructor parameter.
