Use GeoWithinQ as an operator form:

The location of the battle of Zama was not yet in the Roman Republic when the battle took place:

The location of the battle of Zama was in the Roman Republic later in time:

The location of the city of Paris was not in the Roman Republic in year 250 BC:

It was included in the Roman Republic in year 50 BC:

GeoVariant[entity,"UnionArea"] represents the union of all polygons of entity at all times in its history, making GeoWithinQ ignore temporal information:

The United Kingdom is considered to be inside London, since the two entities overlap:

The option "FullyContained"->True excludes regions that extend outside the entity:

London is always considered to be inside the United Kingdom:

Imposing a short time constraint may prevent the function from working:

The default time constraint allows the computation to give the expected result:
