Abstract: A timing method for a sports competition at the same time on different sites (4) around the world. In a first phase, all time bases of the timing devices, of a start coordinator device (3) and of each site are synchronised. Next, a measurement of the transmission times between the start coordinator device and each site is performed to determine a maximum transmission time. The start coordinator device establishes a start time equal to the time of the date of each site and while adding a time difference longer than the determined maximum transmission time. The start time is adapted to each site where the competition takes place to automatically order, by each timing device, the start of the competition at the same time on each site and on the base site of the start coordinator device to have a sports competition taking place live on all competition sites.
