摘要：
A method and system for updating time information of a digital rights management (DRM) includes a time server transmitting a time information message to a consumer electronics (CE) device, the CE device transmitting the time information message to a digital rights management DRM device when the CE device receives the time information message from the time server, and the DRM device updating a present time of the DRM device based on the time information message when the DRM device successfully performs authentication with respect to the time information message which has been transmitted from the CE device.
