To define a yearly time step an id should be configured. Secondly the monthDays of the time steps should be configured.
In this example the yearly time step has 4 monthDays. The start attribute defines the start of the aggregation period and the
end tag defines the end of the aggregation period. The value defines the timestamp used to store the aggregated value of the monthDay itself.
When using the yearly timestep in combination with the accumulation transformations, the value determines a restart moment for the accumulation. For those situations it is advised to set the value at the start of the season.
Monthly time step
A timeStep that defines a pattern of days in a month. This pattern will be repeated every month. Each day in the month can have a different aggregation period. The start of the aggregation period is exclusive and the end of the aggregation period is inclusive.
