A DST(Daylight Saving Time) information update method of a portable terminal is provided to be capable of automatically or manually updating DST information of the terminal, thus world time displayed on the terminal can be more exactly serviced. If DST information received from the first server(100) is changed, the second server(200) transmits a message indicative of the changed information to a portable terminal(300) to demand a connection(201-204). If the second server(200) is connected with the terminal(300), the second server(200) demands DST information stored in the terminal(300)(205,206). If the DST information is received, the second server(200) compares the DST information received from the first server(100) with the DST information of the terminal(300)(207,208). If the compared DST information is not the same, the second server(200) sends the DST information received from the first server(100) to the terminal(300)(209,210). The terminal(300) updates the DST information of the terminal(300) through the received DST information(211).
