Examples of ch.agent.t2.time.SubPeriodPattern

ch.agent.t2.time.TimeIndex
A SubperiodPattern defines a set of higher resolution time points within a base unit. It is applied after the base period pattern, if any. This makes it possible to define a time domain like "at 10:00, 12:30, and 16:45 on every working day" for example, where the base pattern is used to model working days and the sub period pattern is used to define the within day times. A sub period pattern is used in the definition of the time domain implementing "the 3d Friday of the month" in {@link ThirdFriday}. @author Jean-Paul Vetterli @see TimePacker
