It's calculated as such;

actual_check_time - scheduled_check_time

Very advanced mathematics, as you can see. It's the delay between the
time the check was supposed to be run and when it was actually run.

That's a different type of latency. You can use any of the check_ping,
check_fping or check_icmp plugins for that. I've found that check_icmp
performs the best.
