Patent ID: 8578270

Claim:
A method for operating a clock of a mobile terminal including an input unit and a display unit, comprising the steps of: generating a time offset value using a selected time gap value, input to the input unit, while a standard clock keeps track of a current time local to the mobile terminal and is in operation on the basis of a reference clock generating a reference time signal using an internal clock; receiving a clock association value input to the input unit and indicating that either the standard clock is to be used or the reference clock is to be used; receiving a selected offset clock name input to the input unit; creating a new offset clock with the selected offset clock name using the generated time offset value; and displaying the time and the corresponding selected offset clock name of the created new offset clock on the display unit, wherein the created new offset clock operates based on the standard clock when the clock association value indicates that the standard clock is to be used, and the reference clock when the clock association value indicates that the reference clock is to be used.
