Possible options are: "time zero" or "end run"

defaultValidTime

Forecast time after which the modifier is no longer valid. If omitted, this value will be default to the year 3000 and the valid time entry box will not be shown in the modifier display. Note that the only way to get the validTime option available, is to add: <defaultValidTime/> (without attributes or content)

offsetValidTime

an offset to the default valid time, compared to the T0 of the run

defaultvalue

A default value can be defined here.

...

In addition only the reference time series which have the same location(s) as the time series which are being modified will be shown.

resolveInWorkflow
In the element timeSeries is a filter defined which defines which timeseries can be modified with this timeseries. If the element resolveInWorkflow is set than the modifier can be applied to all timeseries in the current workflow to which the defined time
series filter applies. In an IFD-environment the current workflow is the workflow which is associated to the selected topology node.
