This element can be used define a default value for a date/time attribute. If this option is selected the initial value is set to the system time.

When this option is used a checkbox will be shown after the date/time selection box. If this checkbox is selected then a modifier will be created for this attribute with the

current value of the date/time box. When an existing modifier is selected and there is a modified value for the attribute in this modifier then the checkbox will also be selected.

This option is similar to the option useSystemTimeAsDefaultValue, but instead of setting the default value to the system time the default time will be derived from a time series.

A time series set can be configured for this option. The first time of the time series array for which a reliable value is available will be used.


The element <selection> can be used to predefine the list of options which are available for a certain attribute.
