om:time

The Time when the event occurred (mandatory).
This may be given
* in absolute terms as a TimeInstant or TimePeriod
* in approximate terms or relative to an absolute position using the indeterminatePosition attribute
* or using a TimeTopology element (TimeEdge or TimeNode), which provides the option of giving a time relative
to other edges or nodes, either directly (gml) or indirectly (xmml)
* as a TimeGeometricComplex if it is a recurring or repeating event
