1. A method comprising:
receiving an input time stamp at a wireless station in a wireless network, the wireless station having a local counter, the wireless network comprising a plurality of groups of wireless stations, each group running with a different timing clock;
using the input time stamp to overwrite the local counter;
generating an output time stamp based on the value of the local counter at a time a frame comprising the output stamp is predicted to be transmitted; and
transmitting the frame comprising the output time stamp to a further wireless station within the wireless network.
