ABSTRACT:
The invention relates to a method and a device for displaying the time in a mobile telephone, the intention being that there should not be a clock module in said mobile telephone and that the standard used for the communication between the mobile telephone and its base station will not be modified. For this purpose, a counter signal which is transmitted by the base station is initialized in such a way that it always has a specific counter reading at a specific time, as a result of which the time can be calculated in a mobile telephone on the basis of this received counter reading.
