All in one massive SQL statement.  You might find that running each  
layer individually against your POINT is more efficient, however.   
Doing it as a join is probably not optimal, since you're getting no  
particular leverage from the different layers being overlaid.


SELECT
   zipcodes.name,
   urban_areas.name,
   states.state,
   time_zones.gmt_offset,
   counties.county
FROM
   (select 'POINT(-88.050121 41.862380)'::geometry as the_geom) as pt,
   zipcodes,
   urban_areas,
   states,
   time_zones,
   counties
WHERE
   zipcodes.the_geom && pt.the_geom AND
   urban_areas.the_geom && pt.the_geom AND
   states.the_geom && pt.the_geom AND
   time_zones.the_geom && pt.the_geom AND
   counties.the_geom && pt.the_geom AND
   Contains(zipcodes.the_geom,pt.the_geom) AND
   Contains(urban_areas.the_geom,pt.the_geom) AND
   Contains(states.the_geom,pt.the_geom) AND
   Contains(time_zones.the_geom,pt.the_geom) AND
   Contains(counties.the_geom,pt.the_geom)
