Why isn't reltime the default mode? I don't know, but I think in reality you want abstime. Consider a process that does something with items that pass at your machine on a belt conveyor. Then you need to handle one item (say) each 200ms and using reltime means that your latencies add and even with a latency of 1µs you'd miss approx. 1 item per year.
