1. A bridge connecting a plurality of networks, each of which individually has time information varying in a predetermined time period of T, said bridge comprising: a first portal connected to a first network having first time information; a second portal connected to a second network having second time information; a time difference detector for detecting a time difference of the second time information with respect to the first time information; an adjustment value generator for determining a time adjustment value based on the time difference by referring to a table that includes a predetermined correspondence between time differences and time adjustment values, said time adjustment values having a predetermined step of adjustment, an absolute value of each of said time adjustment values being restricted within a predetermined range, said time adjustment value being an integral multiple of T/M (M is an integer greater than 1); and a controller for adjusting the second time information of the second network by the time adjustment value.
