tm_relative_position_integer
tm_relative_position_int( PostTIME , PostTIME ) : integer
Determines the relative position of one instance to another and returns the result as integer according to ISO19108's enumeration TM_RelativePosition. The result is one of the following:
Before = 0, Meets = 1, Overlaps = 2, Begins = 3, BegunBy = 4, During = 5, Contains = 6, Equals = 7, OverlappedBy = 8, Ends = 9, EndedBy = 10, MetBy = 11, After = 12
or '-1' if at least one argument-object is not a primitive (see table below).
Please compare Allen's interval algebra.
