Abstract
A method for time and time zone synchronization and a terminal device. After a terminal registers with a network or roams to the network, the terminal determines whether the network supports a Network Identity and Time Zone (NITZ) function; and if the terminal determines that the network supports the NITZ function, the terminal prompts a user that uses the terminal to use a function of automatic time and time zone synchronization when automatic synchronization is not set for the terminal; or if the terminal determines that the network does not support the NITZ function, the terminal prompts a user that uses the terminal to manually configure time and a time zone. According to the present application, correctness of time and a time zone of the terminal can be ensured.
