You and I can agree on that in principle but there's a lot of reasons an application may read from system time. If the application reads the wrong system time source, then they get unexpected time travel. Even things like the RTC can experience time travel under certain conditions. My point was, using anything other than UTC is just unnecessary complexity and often enough ends in complicated problems.
