Abstract

Embodiments relate to methods and apparatuses (200) for synchronizing a first event (202), having associated therewith a first original event timing value based on a common clock signal, and a second event (204), having associated therewith a second original event timing value based on the common clock signal, wherein the first and the second event (202; 204) experience different delays while travelling through different paths of a distributed computing system (300; 700), and wherein at least one output event (206) is to be determined by an event detector (208) based on the first and the second event (202; 204). The apparatus (200) comprises a delay compensator (210) associated to the event detector (208), the delay compensator (210) having an input (212) for receiving the first and the second event (202; 204) and having an output (214) for forwarding relayed versions (202′; 204′) of the received first and second event to the associated event detector (208), wherein the delay compensator (210) is operable to relay the first and the second event (202; 204) to the associated event detector (208) based on the experienced delays and based on the associated first and second original eve…
