Answer:
Time synchronisation.
Explanation:
Security information and event management (SIEM) is an application service that analyses the real time security alert in a network, which combines both security information management (SIM) and security event management (SEM).
Correlating is SIEM is a function of the SEM component that integrates sources of events, using attributes and common links to make it a useful source of data. It links these events from multiple sources, considering the time synchronisation of the events.
Time synchronisation is a process of coordinate independent clocks event signals due to clock drift, to avoid clock timing at different rate.
