HW timers question (clocksource vs event)

Hi all, I'd like to install one timer that provokes IRQ on timeout to measure IRQ latencies. I can see that in dw_apb_timer.c Linux driver that there is clocksource and event type of timers. Can someone please explain me what is really the difference between clocksource and event type of timers?
