Bounding box operators for temporal types.
The bounding box of temporal values are
Span for temporal BooleansTBox for temporal integers and floats, where the x coordinate is for the value dimension and the t coordinate is for the time dimension. The following operators are defined: overlaps, contains, contained, same, and adjacent.The operators consider as many dimensions as they are shared in both arguments: only the value dimension, only the time dimension, or both the value and the time dimensions.
