A time setup device and a method therefor are provided to set a time accurately regardless of the operation of an image display device. A storing unit(190) stores current time information included in broadcasting information of a broadcasting signal received from the outside. A communication unit(170) communicates with an NTP(Network Time Protocol) server(300) through the Internet(200) and receives global time information. A user interface unit(110) receives a request command of a user. If an NTP clock is selected through the user interface unit(110), a control unit(160) outputs a control signal to set current time on the basis of the time information received from the NTP server(300). A time setup unit(180) compares the time information received through the NTP server(300) with the time information stored in the storing unit(190) according to the control signal of the control unit(160), and sets the current time on the basis of the time information received through the NTP server(300).
