ABSTRACT:
A method for providing time information comprises sending time information to at least one communications device and receiving information indicating error in received time information from at least one of said at least one communications device, said error in received time information having been determined in a communications device. In a communications device, first time information from a communications system is received and second time information with respect to an external time frame is determined. Thereafter an error in first time information based on at least said second time information is determined, and information indicating said error in said first time information is sent to said communications system. A communications device, a communications system and a network element for a communications system are also discussed.
