What does space-time companion mean?

A spatio-temporal companion refers to a person who has been with the diagnosed patient for 14 days in the same spatio-temporal grid (the range is 800 meters *800 meters). In layman's terms, for example, an infected person has been to a place within 14 days, and the trajectory of your 14 days intersects with him. Whether it is a physical brush or a drift in communication signals, it may be considered as a problem of time and space. ?
